Question

The electric meter in a house records:
A. charge
B. current
C. energy
D. power

Answer 1

Hint: The electric meter measures the consumption of electricity by the consumer. Here we have to find the quantity it measures. We know that the kWh meter is used to measure the consumption. From the unit we can find the quantity which the house meter is recording.

Complete answer:
Electricity is the flow of electric power or charge. It is a source of energy. Hence, the electric meter measures the electric energy which is consumed.
Again the electric meter measures the quantity in kWh which is the unit of energy. As energy is also given by product of power and time. Where power is measured in kW and time is measured in hour.

So, the correct answer is “Option C”.

Additional Information:
Electricity which is supplied to the household is AC power supply. AC is the short form of alternating current.
An alternating current power supply is easier to transfer over a long distance with less power loss and also it is cheaper than the direct current power supply. AC power supply transfers voltage to the local transformer near the house or the building which is then transferred to our houses.

Note:
Many get confused with charge or current as electricity is flow of charge so it can be current or charge but the meter here is a kWh meter which is measuring the energy or the power which is used per hour. So the best way to find which quantity an instrument is measuring just see the unit.
