The unit of home electricity energy consumption is?

A. Watt hour
B. Kilowatt hour
C. Joule hour
D. None of these

Answer

Correct Answer: B. Kilowatt hour

Detail about MCQs

The unit of home electricity energy consumption is typically measured in kilowatt-hours (kWh). So, option B, “Kilowatt hour,” is the correct answer. A kilowatt-hour (kWh) is a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour. It is commonly used as a billing unit for energy consumed by residential and commercial customers. For example, if a device with a power rating of 1 kilowatt (or 1000 watts) operates continuously for one hour, it would consume 1 kilowatt-hour of energy. In practical terms, it’s a measure of how much energy is used over time, and it’s what you’re typically billed for by your utility company
