Basically Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.
Electric power is defined as the rate at which electrical energy is consumed in an electrical circuit. The SI unit of power is the watt, which is one joule per second.
Expression
Power = work done / Time
P = VI
= V^2 / R
= I^2 R
