Vedclass · Answer

(B) Electric power $(P)$ is defined as the rate at which electrical energy is consumed or dissipated in an electric circuit.Mathematically,$P = V 	imes I$,where $V$ is the potential difference measured in volts $(V)$ and $I$ is the electric current measured in amperes $(A)$.Therefore,the $SI$ unit of power,the watt $(W)$,can also be expressed as the product of volts and amperes $(V \cdot A)$.- Kilowatt hour $(kWh)$ is a unit of electrical energy.- Watt second $(Ws)$ is also a unit of energy (since $Power 	imes Time = Energy$).- Joule second $(Js)$ is a unit of action.Thus,the correct expression for electric power is volt ampere.

The unit of electric power may also be expressed as:
