Electric Power and Electrical Energy

Electrical energy is the energy that is associated with charged particles because of their positions.

Electric power is the rate at which electrical energy is used in a circuit.

The rate at which electrical work is done is called electric power.

The SI unit for power is the watt (W).

1 W = 1 A 1 V
