- 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 volt-amperes, idle power, wattless power, quadrature power, or volt-amperes reactive. - synonymreactive volt-amperes
