Question

Define electric power. An electrical device of resistance

Answer 1

Electric Power,

rate of consumption of energy or rate of doing work.

P = VI

P = IR× I ........( by ohm's law)

P = I^2 × R

Answer 2

Power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries
