Determine the minimum number of 120-volt, 20-ampere circuit breakers for a continuous load consisting of 63 feet of track lighting to be installed in a dress shop. Calculate the number of circuits to the larger whole number.

Answers

Answer 1

If  we have 20-ampere circuit breakers. The  number of circuits to the larger whole number is: 13.

Number of circuits

Receptacles on a single strap= 180 VA each.

Hence,

VA of the circuit=(Volts x Amperes)/One receptacle

Let plug in the formula

VA of the circuit=(120 volts x 20 amperes)/180 VA

VA of the circuit= 2,400 VA (circuit)/180 VA

VA of the circuit = 13 circuits

Therefore the  number of circuits to the larger whole number is: 13.

when electric power is transmitted over long distance, line losses can be reduced by generating AC rather than DC voltage and by transmitting?

Answers

When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.

What is electric power?

The complete question is attached to the image below.

The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.

The AC transmitted is of high voltage, and the power is low. The equation for current is given,

P = VI

The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.

Therefore, the loss is reduced by transferring high voltage and, low current AC.

Answers

Besides hev and ev motor systems themselves what other systems may use high voltage are the air conditioning compressor, auxiliary battery, and water pump.

Why an excessive voltage is used?

High voltages are utilized in transmission structures due to the fact a better voltage implies a decrease modern-day for a given energy of transmission. With a decrease modern-day, much less warmth is generated withinside the transmission traces and so much less electricity is wasted. Furthermore, it has superb environmental benefits.

To come up with a difficult estimate the common rated energy of the water pump is from 250 watts to 1500 watts. The smaller the water pump, much less is the wattage, much less is the energy consumption, subsequently low is the release and head.Usually, an auxiliary deliver is energy delivery that gives an auxiliary voltage. An instance will clean this up. Say you've got got a switching circuit with score of 220VAC enter and 12VDC output. Enclosure air conditioners may be designed to run on AC and DC voltages.

Answers

If the wire used is 14 awg. The voltage applied to the fixtures is: 8.61 volts.

Voltage applied to the fixtures

First step is to calculate the amperes using this formula

I = P ÷ E

Where:

I =load current (amperes)=?

P =Product of voltage=(6)(20)

E =Electrical circuit's=12

Let plug in the formula

I= (6)(20) ÷ 12

I=120÷12

I= 10 amps

Second step is to calculate the Voltage drop

Using this formula

Vd = [2KIL] ÷ CMA

Where:

Vd= Voltage drop( volts)=?

K=Direct current constant=11.6

I=Load current (amperes)= 10 amps

L =Length in feet=60 feet

CMA=Circular mill area= 4110

Let plug in the formula

Vd= [(2)(11.6)(10)(60)] ÷ 4110

Vd=13,920÷4110

Vd= 3.3869 volts

Third step is to calculate Voltage at fixture

Voltage at fixtures=Electrical circuit's-Voltage drop

Voltage at fixtures=12 - 3.3869

Voltage at fixtures=8.6131 volts

Voltage at fixtures=8.61 volts (Approximately)

Therefore the voltage applied to the fixtures is: 8.61 volts.

Answer:

C) recovers refrigerant in a non-pressurized container

The system dependent (passive) recovery process recovers refrigerant in a non-pressurized container. The correct option is C.

A way of recovering refrigerant from a system without using a pump or heat is known as a system-dependent (passive) recovery process.

Instead, it relies on the system's normal pressure and temperature variations to speed up the recovery process.

A non-pressurized container is commonly connected to the system using this technique, and the refrigerant is then passively allowed to flow inside the container.

The system-dependent recovery procedure, according to Option C, recovers refrigerant in a non-pressurized container.

It entails that the refrigerant is gathered in a container without the need of a pump or additional pressure.
