### Solution:

Concept- This is a common unit, as evidenced by our electricity bills. We can use this to calculate our household's electric energy consumption. It is the amount of energy used in one hour.
Kilowatt-hour is an electrical energy unit. Normally, the unit of energy is the joule. As we all know, power is defined as the rate of energy per unit time.
One watt is defined as one Joule per second of power. That is why we use the unit of power watt (W).
The watt-second is an energy unit equal to one watt of power expended for one second. One kilowatt-hour is defined as one kilowatt or 1000 watts used for one hour (kwh). It is the same as the actual distance travelled by an object in a given amount of time.
1 kilowatt-hour watt-hour
1 kilowatt-hour watts seconds The kWh is not a standard unit of measurement. However, it is widely used to calculate the amount of energy utilised by electrical appliances. As a result, C is the correct answer.
Further information:
The unit of electric energy utilised in household applications is kWh. However, in commercial and industrial uses, it may be written as Kilo Volt Ampere Hour (kVAh). Because of the power factor, this figure is always greater than the kWh. The power factor is the ratio of actual power to apparent power. The actual power is measured in kWh, while the apparent power is measured in kVAh. Because inductive loads generally waste a lot of power while doing nothing. It can assist you in understanding the entire energy consumption for a given time period.
Hence, option 3) is correct.
