Power
Electrical POWER pertains to the rate at which work is being done. Work is done whenever a force
causes motion. The instantaneous rate at which work is done is called the electric power rate and is
measured in WATTS.
Formulas for power in dc circuits are:
For ac circuits:
True power:
True power is measured in watts.
