  • The power in an AC circuit which cannot perform work. It is calculated by the following formula: P = I·V·sinθ, where P is the power in watts, I is the current in amperes, V is the voltage in volts, and sinθ is the sine of the angular phase difference between the current and the voltage. Also called reactive power, idle power, quadrature power, volt-amperes reactive, or reactive volt-amperes.
