WebIn general, power is defined as the rate at which work is done, or energy is used, per unit of time. Electric power specifically refers to the rate in which a source of electricity produces energy, or refers to the rate in which an electrical device, appliance, or piece of equipment converts electrical energy into other forms of energy. WebPower is defined as the rate energy ( \text U U) is transformed or transferred over time. We measure power in units of joules/second, also known as watts. An electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge.
