The correct response is a. Flame sensor. Flame sensor should be tested.
The flame sensor, which is a brief, thin metallic rod, generates a modest electrical current to signal whether a flame is burning inside the furnace. The current moves from the sensor to detect the heat from a flame as the gas valve opens to initiate combustion. An essential safety component of your gas heating system is a flame sensor. Your gas furnace will really ignite the gas during the ignition cycle using a spark or a hot surface ignitor. A current of electricity is produced by the flame sensor as the gas is ignited. If your furnace doesn't have a flame sensor, it will continue to release gas even when nothing is there to ignite it, which can lead to dangerous gas accumulation.

A variable power supply is connected to a coil and an ammeter, and the time dependence of the ammeter reading is shown. A nearby coil is connected to a voltmeter.
The resistance for a perfect circuit will be calculated as R= I/V = 6/2 = 2. A variable power supply is one that has several controls that allow the user to quickly change the output voltage and, occasionally, current.
The most common tool for adjustment is a potentiometer, although other tools include analog control voltage, digital input, autotransformer, etc. The measured voltage is the total of the voltages across the ammeter and the resistance, albeit, with a non-ideal ammeter, the ammeter's resistance is not zero. Otherwise known as V>V R, measured voltage (V) is greater than the voltage across the resistor (V R).
As a result, the measured resistance (2) is higher than the real resistance.

You have been hired by a homeowner to install a ceiling fan and light kit in a living room. The living room luminaire (light fixture) being used at the present time contains two 60-W lamps. After locating the circuit in the panel box, you find that the circuit is protected by a 15-A circuit breaker and is run with 2.5mm² copper wire. After turning on all lights connected to this circuit, you have a current draw of 8.6 A and a voltage of 120V. The ceiling fan light kit contains four 60-W lamps, and the fan has a maximum current draw of 1.6 A. Can this fan be connected to the existing living room circuit? Recall that a continuous-use circuit should not be loaded to more than 80% of its rated capacity.
Answer:
No, you cannot add the ceiling fan to the circuit.
Explanation:
120V/60W=0.5A (V/W=A)
0.5A*4=2A (you have 4 60W lamps)
2A+1.6A=3.6A
3.6Ax0.125=0.45A (continuous load appliances must have amperage rated at 125% according to USA NFPA 70)
0.45A+3.6A=4.05A
4.05A+8.6A=12.65A
Assuming all devices on the circuit are ON, there would be a total current draw of 12.65A (after adding the ceiling fan). 80% of 15A is 12A.

Slow down: reduce your speed to allow for extra time to react to changing conditions.Use headlights: turn on your headlights to increase your visibility and to make it easier for other drivers to see you.Keep a safe distance: increase the distance between you and the vehicle in front of you to allow for extra stopping time.Use windshield wipers and defrosters: keep your windshield clean and clear to improve visibility.Be prepared for sudden stops: be aware of the traffic around you and be prepared to brake quickly if necessary.Watch for pedestrians and bicycles: be extra cautious when approaching intersections and crosswalks, as visibility may be poor and it can be harder to see pedestrians and bicycles.Avoid sudden movements: avoid sudden movements, such as changing lanes or making turns, as it can be harder to judge distances and speeds in poor visibility conditions.Pull over if necessary: if visibility becomes extremely poor, it may be safer to pull over and wait for conditions to improve.It's important to remember that even when you are following all the safety guidelines, it's still hard to predict what other drivers may do, so always stay alert and drive defensively.

Three gears on the machine are interlocked. Gear A rotates at 30 rotations per minute in a clockwise direction and contains 18 teeth. Gear B rotates anticlockwise x rotations, which is 8.25.
Which three major revolutions came first, in ordeThe first one is the Industrial Revolution, which started in the late eighteenth century; the second was the Demographic Revolution, which began in the late nineteenth; and the third, the Happiness Revolution, which began in the late twentieth century, is currently underway.
Calculation
Gear A turns clockwise and has 54 teeth
Gear B turns counterclockwise and has 36 teeth
gear A makes 5.5 rotations
One of the gears is driving the other hence the distance covered by each of the gears is constant.
The distance is the product of the number of rotations and the number of teeth and this should be a constant
Therefore, let the number of rotations of gear B be x
54 teeth * 5.5 rotations = 36 teeth * x rotations
x rotations = ( 54 teeth * 5.5 rotations ) / 36 teeth
x rotations = 54/36 * 5.5
x rotations = 1.5 * 5.5
