## Definition

### Electronics

- The
__power__in an__AC circuit__which cannot perform work. It is calculated by the following formula:=*P*, where*I·V·sinθ*is the power in watts,*P*is the current in amperes,*I*is the*V*__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, wattless power, volt-amperes reactive, or reactive volt-amperes.
