Energy Meter Experiment Procedures

The video tutorial explains how to set up and conduct an energy meter experiment. It covers the circuit diagram, connection details, and the procedure for taking readings. The experiment involves using an energy meter, AM meter, and voltmeter to measure energy consumption. The tutorial provides step-by-step instructions on making connections, starting the experiment, and taking accurate readings. Observations are made by noting the time taken for the energy meter's disc to complete revolutions, which is then used for calculations.

What is the primary purpose of the energy meter experiment?

• To compare different types of energy meters

• To test the durability of electrical wires

• To measure the energy consumption using a single-phase energy meter

• To measure the voltage in a circuit

Why is it important to connect the phase and neutral lines correctly in the energy meter?

• To prevent the circuit from overheating

• To ensure the energy meter functions properly

• To increase the lifespan of the energy meter

• To reduce the cost of the experiment

Where should the ammeter be connected in the circuit?

• On the line of phase from phase to wire one

• Directly to the energy meter

• Between the phase and neutral lines

• In parallel with the voltmeter

What should be done before starting the experiment?

• Disconnect the ammeter

• Switch on the voltmeter to the AC supply

• Connect the voltmeter to the DC supply

• Ensure all loads are switched on

What is the first step in the procedure of the experiment?

• Switch on all the loads

• Take the voltmeter and ammeter readings at zero load

• Connect the energy meter to the power supply

• Adjust the phase and neutral lines

What happens to the energy meter when the load is increased?

• It shows a constant reading

• It stops rotating

• It rotates very slowly

• It starts to rotate quickly

How is the time for one revolution of the energy meter's disc measured?

• Using a voltmeter

• Using a stopwatch

• By counting manually

• Using an ammeter

What should be done after noting the time for one revolution?

• Divide it by 2

• Add it to the previous reading

• Multiply it by 10

• Multiply it by 5

What is the expected voltmeter reading when two lights are switched on?

• 110 to 120 volts

• 220 to 230 volts

• 300 to 310 volts

• 50 to 60 volts

What is the final step in the experiment procedure?

• Reset the voltmeter and ammeter

• Take the final readings and perform calculations

• Switch off all the loads

• Disconnect the energy meter
