a) With aid of diagram explain the basic principles of Induction motor operation.

b) A four-pole 10-hp, 460 V motor is supplying its rated power to a load at 50 Hz frequency. Its rated speed is 1450 rpm. Calculate:

I. The motor speed

II. The slip frequency

III. The slip frequency and slip speed when it is supplied by a 230 V, 25 Hz source.

Answers

The negative values for slip frequency and slip speed indicate that the rotor is operating in the opposite direction to the rotating magnetic field.

a) **Induction motor operation** can be explained through the following diagram:

[Insert diagram illustrating the basic principles of induction motor operation]

The stator of the induction motor contains a set of stationary windings, while the rotor has a set of windings arranged in the form of bars or conductors. When an AC voltage is applied to the stator windings, it produces a rotating magnetic field. This magnetic field induces a current in the rotor windings through electromagnetic induction. The interaction between the rotating magnetic field and the induced rotor current generates a torque, causing the rotor to rotate. This rotation continues due to the relative motion between the rotating magnetic field and the rotor.

b)

I. To calculate the **motor speed**, we can use the formula:

Motor Speed (in RPM) = (120 * Frequency) / Number of Poles

Given:

Frequency = 50 Hz

Number of Poles = 4

Motor Speed = (120 * 50) / 4 = 1500 RPM

II. The **slip frequency** can be determined using the formula:

Slip Frequency = Motor Speed - Synchronous Speed

Given:

Motor Speed = 1450 RPM

Synchronous Speed = (120 * Frequency) / Number of Poles

Synchronous Speed = (120 * 50) / 4 = 1500 RPM

Slip Frequency = 1450 RPM - 1500 RPM = -50 RPM

III. To calculate the **slip frequency and slip speed** when supplied by a 230 V, 25 Hz source, we first need to determine the new synchronous speed:

Synchronous Speed = (120 * 25) / 4 = 750 RPM

Slip Speed = Synchronous Speed - Motor Speed = 750 RPM - 1450 RPM = -700 RPM (negative sign indicates that the rotor is moving in the opposite direction of the rotating magnetic field)

Slip Frequency = Slip Speed = -700 RPM (since slip speed is the same as slip frequency)

Please note that negative values for slip frequency and slip speed indicate that the rotor is operating in the opposite direction to the rotating magnetic field.

For x[n]={1,0,2,1), find x[2n+2]

Answers

When n = 2, 2n+2 = 6. x[2n+2] = x[6] = 1.

When n = 3, 2n+2 = 8. x[2n+2] = x[8] = 0.

When n = 4, 2n+2 = 10. x[2n+2] = x[10] = 2.

When n = 5, 2n+2 = 12. x[2n+2] = x[12] = 1.

Given the sequence x[n]={1, 0, 2, 1}, we are to determine x[2n+2].

To obtain the value of x[2n+2], we must first determine the value of 2n+2 for any integer n.

The value of 2n+2 is 2 times n plus 2.

It implies that the sequence x[n] is always even.

When n = 0, 2n+2 = 2. x[2n+2] = x[2] = 2.

When n = 1, 2n+2 = 4. x[2n+2] = x[4] = undefined (since there are only four values in the sequence, and x[4] does not exist).

When n = 2, 2n+2 = 6. x[2n+2] = x[6] = 1.

We know that x[n] is periodic with a period of 4 since it repeats every four values.

As a result, when n is an integer greater than or equal to 2, we can use this knowledge to determine x[2n+2].

When n = 2, 2n+2 = 6. x[2n+2] = x[6] = 1.

When n = 3, 2n+2 = 8. x[2n+2] = x[8] = 0.

A 50-Hz, 100-MVA, four-pole, synchronous generator has an inertia constant of 3.5 s and is supplying 0.16 pu power on a system base of 500 MVA. The input to the generator is increased to 0.18 pu. Determine (i) the kinetic energy stored in the moving parts of the generator and (ii) the acceleration of the generator. If the acceleration continues for 7.5 cycles, calculate (iii) the change in rotor angle and (iv) the speed in rpm at the end of the acceleration.

Answers

To solve this problem, we'll use the following formulas:

(i) Kinetic Energy (KE) = 0.5 * Inertia Constant * Synchronous Speed^2

(ii) Acceleration (A) = (Change in Power) / (Inertia Constant * Base MVA)

(iii) Change in Rotor Angle (Δθ) = Acceleration * (Number of Cycles)

(iv) Speed (N) = Synchronous Speed - (Δθ * (60 / Number of Cycles))

Given data:

Frequency (f) = 50 Hz

Apparent Power (S) = 100 MVA

Inertia Constant (H) = 3.5 s

Power Increase (ΔP) = 0.18 pu - 0.16 pu = 0.02 pu

System Base MVA = 500 MVA

Number of Cycles = 7.5

First, let's calculate the synchronous speed:

Synchronous Speed = (120 * f) / Number of Poles

                 = (120 * 50) / 4

                 = 1500 rpm

(i) Kinetic Energy (KE) = 0.5 * Inertia Constant * Synchronous Speed^2

                       = 0.5 * 3.5 * (1500)^2

                       = 3,937,500 J

(ii) Acceleration (A) = (Change in Power) / (Inertia Constant * Base MVA)

                    = (0.02 pu) / (3.5 s * 500 MVA)

                    ≈ 1.142 x 10^-5 pu/s

(iii) Change in Rotor Angle (Δθ) = Acceleration * (Number of Cycles)

                               = (1.142 x 10^-5 pu/s) * 7.5 cycles

                               ≈ 8.57 x 10^-5 pu

(iv) Speed (N) = Synchronous Speed - (Δθ * (60 / Number of Cycles))

             = 1500 rpm - (8.57 x 10^-5 pu * (60 / 7.5))

             ≈ 1499.852 rpm

Therefore, the results are:

(i) The kinetic energy stored in the moving parts of the generator is approximately 3,937,500 J.

(ii) The acceleration of the generator is approximately 1.142 x 10^-5 pu/s.

(iii) The change in rotor angle after 7.5 cycles is approximately 8.57 x 10^-5 pu.

(iv) The speed at the end of the acceleration is approximately 1499.852 rpm.

Answers

a. the no-load operating speed of the motor is 50 RPM. b. the electrical frequency of the rotor under full-load condition, for a speed regulation of 5%, would be approximately 2.381 Hz.

a) To find the no-load and full-load operating speeds of the motor, we can use the formula:

Speed (in RPM) = (120 * Frequency) / Number of Poles

Given:

Number of poles (P) = 6

1. For the no-load condition:

Electrical frequency of the rotor (f) = 2.5 Hz

Speed (no-load) = (120 * 2.5) / 6

              = 50 RPM

Therefore, the no-load operating speed of the motor is 50 RPM.

2. For the full-load condition:

Electrical frequency of the rotor (f) = 6.3 Hz

Speed (full-load) = (120 * 6.3) / 6

                 = 1260 RPM

Therefore, the full-load operating speed of the motor is 1260 RPM.

b) The speed regulation of the motor can be calculated using the formula:

Speed Regulation (%) = [(No-Load Speed - Full-Load Speed) / Full-Load Speed] * 100

Given:

No-Load Speed = 50 RPM

Full-Load Speed = 1260 RPM

Speed Regulation = [(50 - 1260) / 1260] * 100

                = -90.48%

Therefore, the speed regulation of the motor is approximately -90.48%.

c) To determine the electrical frequency of the rotor under full-load condition for a desired speed regulation of 5%, we can rearrange the formula for speed regulation:

Speed Regulation = [(No-Load Speed - Full-Load Speed) / Full-Load Speed] * 100

Rearranging the formula:

Full-Load Speed = No-Load Speed - (Speed Regulation/100) * Full-Load Speed

Given:

No-Load Speed = 50 RPM

Speed Regulation = 5%

Let's solve for the electrical frequency of the rotor at full-load:

Full-Load Speed = 50 - (5/100) * Full-Load Speed

(1 + 5/100) * Full-Load Speed = 50

1.05 * Full-Load Speed = 50

Full-Load Speed = 50 / 1.05

              = 47.62 RPM

Using the formula for speed:

Speed (full-load) = (120 * Electrical Frequency) / Number of Poles

47.62 = (120 * Electrical Frequency) / 6

Electrical Frequency = (47.62 * 6) / 120

                   = 2.381 Hz

Therefore, the electrical frequency of the rotor under full-load condition, for a speed regulation of 5%, would be approximately 2.381 Hz.

The transformer ratio in the circuit of an idealized forward converter is 2:1 if the input voltage Vd is 40 V, duty cycle of 0.5 and an output power of 50 W with a resistive load of 50Ω.

The transformer ratio is calculated based on the output voltage of the transformer, Vout.The voltage rating of the transformer will be calculated based on the output voltage. The transformer is connected in the forward configuration, in which the primary side of the transformer is in series with the input voltage source, and the output voltage is acquired across the secondary winding.

The duty cycle of the converter is the proportion of time that the switch is turned on. The switch will be turned on for half the time in a 50% duty cycle. In this way, the input voltage is transmitted to the transformer when the switch is turned on, and no power is transmitted when the switch is turned off.

Answers

The root locus for the given unity feedback system can be obtained by analyzing the poles and zeros of the open-loop transfer function To sketch the root locus, we need to analyze the poles and zeros of the open-loop transfer function.

The open-loop transfer function for the given unity feedback system is given as: G(s) = P(s) * C(s) = K * (s + 4) / (s * (s + 5)) We start by identifying the poles and zeros of the transfer function. The transfer function has a single zero at s = -4 and two poles at s = 0 and s = -5. Next, we determine the angles and magnitudes of the branches of the root locus. The angles of departure and arrival for each branch are calculated using the angle criterion, and the magnitudes of the branches are calculated using the magnitude criterion. The root locus starts from the open-loop poles and moves towards the open-loop zero. As the gain K increases, the root locus branches move towards the zeros and may converge or diverge depending on the gain value. By analyzing the root locus, we can determine the regions of the gain parameter K that result in stable closed-loop system behavior. The root locus plot provides insights into the stability and transient response characteristics of the system.

Ancient Near Eastern art encompassed various regions with distinct artistic expressions, highlighting their diverse priorities. One such example is the Stele of Hammurabi, an art piece from Babylonia (present-day Iraq) dating back to the 18th century BCE. This monumental stone relief depicts King Hammurabi receiving the laws from the god Shamash. The emphasis on the divine figure and the act of receiving laws represents the Babylonian emphasis on justice and the divine authority of the king. In contrast, the Standard of Ur, an artifact from Sumer (southern Mesopotamia, now Iraq) dating to the 3rd millennium BCE, demonstrates a different priority. This mosaic-like panel features a narrative scene depicting a royal banquet and a war procession. It showcases the Sumerian focus on societal hierarchy, military prowess, and the glorification of their rulers.

Part 2: [photo of the funerary mask of Tutankhamun and an aerial view of the Giza pyramids complex, see the attachment]

Egyptian art's enduring style, which remained relatively consistent for millennia, held profound significance. An example that sheds light on the significance of Egyptian artistic style is the funerary mask of Tutankhamun, dating back to the 14th century BCE. The mask exhibits the distinct stylization seen in Egyptian art, characterized by rigid and formalized poses, frontal perspective, and idealized features. This specific stylization was intended to convey eternal and divine qualities. The Egyptians believed that by representing figures in a timeless, idealized manner, they could capture the essence of the individual for eternity. This idealization also reflected their perception of an orderly and unchanging world governed by divine forces. Moreover, the concept of the cities for the dead, such as the famous complex of pyramids and tombs in Giza, exemplifies the Egyptian belief in the afterlife and their commitment to preserving the deceased's physical body for eternity. These cities, meticulously constructed with grandeur and complexity, aimed to ensure the continuity of life beyond death and the preservation of the individual's status and identity.

(d) How long would it take if you had an AC Level 2 charging unit (220VAC, 80 A)? (e) What is the effect of selecting the charger level on the EV owner and the electric grid?

Answers

a) To design the battery pack for an all-electric vehicle, assuming single cell specifications: Vcell 4.2V, Capacity cell = 5.5Ah, the number of series and parallel cells required to meet the specifications of the battery pack are as follows

:Energy Pack = 60 kWhV

pack = 400 V

Number of series cells,

Ns = Vpack/Vcell

= 400/4.2

= 95.23, ~96.

Number of parallel cells, Np = Energy Pack/(Vcell × Capacity cell × Ns)

= 60×10^3/(4.2×5.5×96)

= 25.2, ~26.

Therefore, the battery pack should have 96 series cells and 26 parallel cells.

b) The power required by the electric motor is 200 kW. The maximum current to be drawn from every cell can be calculated using the formula

,I = P/V = 200×10^3/400

= 500

A.Maximum current drawn from every cell,Imax = I/Np = 500/26 = 19.23 A.The maximum current that can be drawn from every cell is 19.23 A.

C-rate = Imax/Capacity cell

= 19.23/5.5 = 3.5 C.

The AC Level 1 charger provides 120VAC and 16A. Assuming that the pack is fully discharged, the time taken to fully recharge the battery pack can be calculated using the formula

,T = Energy Pack/Power

= 60×10^3/(120×16)

= 31.25 h.

The AC Level 2 charger provides 220VAC and 80A. Assuming that the pack is fully discharged, the time taken to fully recharge the battery pack can be calculated using the formula,

T = Energy Pack/Power

= 60×10^3/(220×80)

= 3.41 h.
The selection of the charger level has a significant impact on the EV owner and the electric grid. The Level 1 charger takes a longer time to recharge the battery pack, which may not be suitable for long-distance travel. On the other hand, the Level 2 charger is more suitable for long-distance travel as it takes less time to recharge the battery pack. However, it draws a higher current, which may put a strain on the electric grid. Therefore, the selection of the charger level should be based on the specific needs of the EV owner, taking into consideration the impact on the electric grid.

Answers

The given ideal refrigeration cycle uses refrigerant R134a which operates steadily between 140 kPa and 900 kPa.

We need to determine the rate of cooling of the refrigerated space per kg R134a (kJ/kg).

Let,

h1 = Enthalpy of refrigerant R134a at the beginning of the

processh4 = Enthalpy of refrigerant R134a at the end of the

processh2 = Enthalpy of refrigerant R134a after

compressionh3 = Enthalpy of refrigerant R134a after expansion

The coefficient of performance of a refrigerator (COP) is given by:

COP = (Refrigeration effect) / (Work input)

For a refrigerator,

COP = QL / W = h1 - h4 / h2 - h1

The refrigeration effect per unit mass of the refrigerant is given by:

QL = h1 - h4

The work done per unit mass of the refrigerant is given by:

W = h2 - h3

From the first law of thermodynamics for a cycle,

Work input = QL + W

Here, W is negative as work is done on the system.

The rate of compressor work per kg R134a is 0.652 kJ/kg.

the correct answer is option (g).

Fatigue Behaviour & Failure A tubular component failed in fatigue. Failure analysis included characterisation of the fracture surface. It was found that that the failure started near a small surface scratch with a depth of 0.05 mm. Assume the stress in the frame tube varies smoothly. It holds for this case R = -0.25 and the maximum stress is 400 MPa. One complete cycle takes 0.1 seconds. The tube has a diameter of 4 cm and a wall thickness of 2.5 mm. a) Take a point at the tube surface wall and sketch the stress in this point as a function of time for one loading cycle . For this material it is known: • Kic= 25 MPa.m ¹/2 • Kth=2.5 MPa.m ¹/2 Y = 1 m = 4 • c = 2.10-¹¹ (MPa)-4.m¹¹ b) How much is the relevant difference between the maximum and minimum stress in this case for fatigue? Explain your answer . c) Calculate the crack length when failure of the tube occurred . d) Calculate the number of cycles to failure under these conditions (1,5 point). e) Residual stresses have a strong effect on fatigue life of a construction. When do they have positive and when do they have a negative effect? Give an example of both (1,5 point).

Answers

a) Stress as a function of time:

The peak stress is as follows:

σ max = - σ min R/(1-R)

= -400MPa*0.25/(1-0.25)

= 100 MPa

The stress amplitude is as follows:σ a = (σ max - σ min)/2

= (100 MPa - (- 400 MPa))/(2)

= 250 MPa

The maximum stress occurs when

t = 0 s,

t = 0.1 s and

t = 0.2 s. T

therefore, the time required for one cycle is 0.2 seconds. So, The stress is:

σ = 100 sin(2πf(t - T/4)) MPa

where f = frequency

= 1/T = 5 Hzb) The relevant difference between the maximum and minimum stress in this case for fatigue is equal to the stress amplitude, i.e., 250 MPa.The stress amplitude is the difference between the minimum and maximum stress in the cycle. It indicates how much a material is subjected to a varying load.

c) Crack Length:

K = σ√πa

= Kic + Yσ√πa d

= K2 / (πσ√πa)

= [Kic + Yσ√πa]2 / (πσ√πa)

If we set d equal to the critical crack length, which is assumed to be equal to the wall thickness of the tube, we can determine the maximum permissible length of the crack

.a = (Kic2 - (πσ√πd)c2) / (Y2σ2π)

= [25² - (π x 100 x 2.5 x 10-3)²] / [(1 x 400² x π)]

= 5.12 mm

Since the crack initially started with a depth of 0.05 mm, the final crack length is 5.12 + 0.05 = 5.17 mm.

d) Number of cycles to failure:

:Nf = [(1 / c)(da / dN)](ΔK)

Nf = [(1 / 2.10-11)(2.5 x 10-9 / 5.17 x 10-3)](250 MPa√m)

what other options to replaces a zener diode to get a stabilised
DC voltage

Answers

A Zener diode is a popular component used to stabilize DC voltage in a circuit. However, in some cases, it may not be practical or readily available. In such cases, there are alternative options that can be used to replace the Zener diode and achieve a stabilized DC voltage.

One such option is the voltage regulator IC (integrated circuit). This component is readily available and can be used in place of a Zener diode. Voltage regulator ICs can provide output voltages ranging from a few volts to several hundred volts. They also provide a stable output voltage regardless of variations in input voltage and load.Another option is to use a transistor to achieve a stabilized DC voltage. This is done by creating a simple transistor circuit with the transistor configured as an emitter follower.

The output voltage is stabilized by the voltage drop across the base-emitter junction of the transistor. The voltage drop is typically around 0.6 volts and can be varied by adjusting the value of the base resistor. This method is simple and cost-effective, but may not be as stable as using a Zener diode or voltage regulator IC.Other options include using a series voltage regulator or a shunt voltage regulator. These methods are more complex and require additional components, but they can provide very stable output voltages. Overall, there are several options available for replacing a Zener diode and achieving a stabilized DC voltage.

The per-unit reactance to the point of the fault is the impedance of the Thevenin equivalent of the system divided by the base impedance.

Answers

A 10 bit ADC has a lower reference voltage VREF minus of OV and an upper reference voltage VREF plus of 3.3 V. The hex output is option c) 0x386 is correct.

The given ADC is 10-bit ADC, and it has a lower reference voltage VREF minus of 0V and an upper reference voltage VREF plus of 3.3V.

We need to determine the hexadecimal output code that corresponds to 2.91V.To calculate the hexadecimal output code, first we need to determine the voltage resolution of the ADC as follows:

VREF = VREF plus - VREF minus= 3.3 V - 0 V= 3.3 V

Resolution = VREF / 2^n

where n is the number of bits

Therefore, Resolution = VREF / 2^n= 3.3 V / 1024= 3.22 mV

So, the voltage resolution of the ADC is 3.22 mV.

To calculate the output code, we need to divide the input voltage by the voltage resolution and then truncate any fractional part.

The formula to calculate the digital output is given by:

Output Code = Vin / Resolution

We can substitute the given values into the above formula and find the output code.

Output Code = Vin / Resolution= 2.91 V / 3.22 mV= 903.1

Now we have to convert the decimal output code into a hexadecimal code.

To convert the decimal number into a hexadecimal number, we have to use the repeated division-by-16 method. This method consists of dividing the decimal number by 16 until we get a quotient equal to zero.

Then we have to write the remainders, starting from the last one obtained and writing up to the first remainder obtained. Let's perform the repeated division-by-16 method to convert the decimal number into hexadecimal.

903 ÷ 16 = 56 remainder 712 ÷ 16 = 8 remainder 04

We can see that the quotient is zero, so we stop. Now we have to write the remainders in the reverse order:48HEX is the hexadecimal output code for 2.91 V.

Therefore, the option c) 0x386 is the correct option.

Each flip flop stores one bit of data, and a clock signal synchronizes the shifting of data through the register. A sketch illustrating a shift register shows multiple flip flops connected in a chain, with the output of one flip flop connected to the input of the next.

In a parallel-in-serial-out (PISO) register, data is loaded in parallel into the register and then shifted out serially.

Load # 3 ; 5000KVA at 0.707 lagging power factor

If alternator A is adjusted to carry an armature current of 750 amperes at 0.84 lagging power factor. Calculate the armature current and the power factor of alternator B.

Given data: Load # 1 ; 8000KVA at unity power factor Load # 2 ; 6000KVA at 0.8 lagging power factor Load # 3 ; 5000KVA at 0.707 lagging power factor Alternator A armature current is 750 A at 0.84 lagging power factor.

Let the armature current and the power factor of the alternator B be I2 and pf2 respectively.

Now, we know that power factor = cosφAlternator A is adjusted to carry an armature current of 750 A at 0.84 lagging power factor.

This means, cos φ1 = 0.84 => φ1 = cos-1 (0.84) = 32.61°As power factor (pf1) of alternator A is given as 0.84,

hence sin φ1 = sin (90°-φ1) = sin (90°-32.61°) = 0.5463

The active power of alternator A is 8000 + 6000 cos 36.87° + 5000 cos 45° = 17421.04 kW

The reactive power of alternator A is 6000 sin 36.87° + 5000 sin 45° - 750 sin 32.61° = 5807.12 kVAR.

The apparent power of alternator B will be (8000+6000+5000) = 19000 kVA The apparent power of the system is the addition of the apparent power of alternator A and alternator B, which is 18327.16 + 19000 = 37327.16 kVA

Thus, I2 = 37327.16/(6.6 × √3 × 0.707) = 4020.45 A From the power triangle of alternator B, we know that cos φ2 = P2/S2 = (19000 cos φtotal - 17421.04)/√(19000² + 37327.16² - 2 × 19000 × 37327.16 × cos 20.93°

Solution:

Answers

The poles of H(z) are located at z = 0 and z = ∞, while there are no zeros. The region of convergence (ROC) is the region outside the pole at z = 0, i.e., |z| > 0.

The output Y(z) is obtained by multiplying the input X(z) with the transfer function H(z). The output sequence y[n] can be obtained by taking the inverse z-transform of Y(z). To determine the input sequence x[n], we take the inverse z-transform of X(z).

In the z-domain, the poles of H(z) correspond to the points where the system becomes unstable or exhibits certain characteristics. In this case, the pole at z = 0 indicates a right-sided sequence with exponential decay. The absence of zeros means that there are no points where the transfer function is zero.

The region of convergence represents the range of z-values for which the z-transform converges and the system is stable. In this case, the ROC is |z| > 0, meaning the system is stable for all values of z except at z = 0.

Multiplying X(z) with H(z) gives the z-transform of the output sequence Y(z). Taking the inverse z-transform of Y(z) yields the output sequence y[n], which represents the system's response to the input sequence.

Similarly, taking the inverse z-transform of X(z) gives the input sequence x[n], which is the original sequence that led to the given z-transform X(z).

In the circuit diagram above, a Light Dependent Resistor (LDR) is used as the sensor to detect the light intensity. The LDR is placed near the lamp so that it can detect when the light from the lamp is not required. When the light intensity becomes low (i.e. in the evening or at night), the LDR resistance decreases, which causes the voltage at the base of the transistor (T1) to increase.

This, in turn, increases the current flowing through the transistor, which turns on the lamp (D1) via relay (RL1). The relay is used to isolate the lamp from the transistor, as the transistor will not be able to handle the current required to operate the lamp directly.

b) The system is not BIBO stable if there exists a bounded input signal that produces an unbounded output signal. A common example of an input signal that produces an unbounded output from a system is the unit step function.

When the unit step function is used as an input signal, it is possible for the output signal to grow without bound if the system is not BIBO stable.

c) The transfer function H(z) of the given system can be found by applying the Z-transform to the difference equation:

y[n] + 2y[n-1] + y[n-2] = x[n] + 2x[n-1]

Using the Z-transform notation, we have:

Y(z) + 2z^{-1}Y(z) + z^{-2}Y(z) = X(z) + 2z^{-1}X(z)

Simplifying this expression, we obtain:

H(z) = \frac{Y(z)}{X(z)} = \frac{1+2z^{-1}}{1+2z^{-1}+z^{-2}}

The transfer function of the given system is:

H(z) = \frac{Y(z)}{X(z)} = \frac{1+2z^{-1}}{1+2z^{-1}+z^{-2}}

mass transfer in binaries occurs when one giant swells to reach the:

Answers

Mass transfer in binaries occurs when one giant swells to reach the Roche lobe. A binary system refers to two astronomical bodies that are close to one another and are gravitationally connected.

In general, one of the two stars is less massive and dimmer than the other, which is brighter and more massive. As the less massive star expands and grows, it may get to the point that its outer atmosphere extends past its Roche lobe and the more massive star's gravitational pull.

The Roche lobe is a teardrop-shaped figure that encircles two gravitationally linked celestial bodies, with one of them being denser than the other. When one of the stars extends past the Roche lobe, mass transfer in binaries occurs. This happens because the mass moves from the more massive star to the less massive star.

Which of the following statements correctly describe the functions of a freewheel diode in a switching circuit with a single switch? (Multiple answers possible, but wrong answers will deduct marks) O A freewheel diode functions as an uncontrolled switch - its switching state is only reliant on the voltage applied across it. O For an inductive load in a switching circuit, a freewheel diode must be placed in parallel with the inductive load. O A freewheel diode is a fully controllable switch. ✔✓ For an inductive load in a switching circuit, a freewheel diode provides a path for the load current to circulate, thus preventing an inductive voltage spike that could damage the switch immediately after it is turned off. O For an inductive load in a switching circuit, a freewheel diode must be placed in series with the inductive load to store energy.

Answers

A freewheel diode provides a path for the load current to circulate, thus preventing an inductive voltage spike that could damage the switch immediately after it is turned off is the correct statement to describe the function of a freewheel diode in a switching circuit with a single switch.

A freewheel diode is not a fully controllable switch. It is also not a switch that functions as an uncontrolled switch because its switching state is not only reliant on the voltage applied across it. For an inductive load in a switching circuit, a freewheel diode must be placed in parallel with the inductive load because it provides a path for the load current to circulate.

The freewheel diode has a reverse bias in this configuration, so it does not contribute to the current flow. It will, however, dissipate the energy stored in the inductive load when the switch is turned off.

Q: a): Find beta circuit and its expression. b): Find R11 and R22 from beta circuit. c): Find the expresson of the open loop gain (A). Shunt-Series feedback

Answers

The beta circuit The β circuit consists of the amplifier with its input and output ports, in addition to two impedances which form the feedback network.

The feedback network is typically composed of an impedance (Rf) connected in series with the output port, and a second impedance (R1) connected in shunt with the input port. The β circuit is similar to the voltage divider. Below is the circuit diagram.

The values of R11 and R22First, we need to convert the β network into a T network by replacing R1 with an equivalent resistance of Req. Then R22 is given by the Req = Rf || (R1 + R2)Here || denotes parallel combination.R22 = Req + R2(c) The open-loop gain expression (A)Now that we have found the values of R11 and R22.
