$1\,kWh$ is a unit of power. This statement is true or false? If it is wrong,then correct it.
(FALSE) The statement is false.
$1\,kWh$ (kilowatt-hour) is a unit of energy,not power.
Power is defined as the rate of doing work,measured in watts $(W)$ or kilowatts $(kW)$.
Energy is defined as the product of power and time,which is why $1\,kWh = 1\,kW \times 1\,h = 1000\,W \times 3600\,s = 3.6 \times 10^6\,J$.
