 | | Electric power is the amount of work done by an electric current in a unit time. |
 | | Electric power, like mechanical power, is represented by the letter P in electrical equations, and is measured in units called watts (symbol W), after Scottish engineer James Watt. |
 | | The portion of power flow that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as real power. |
