# idle power

## Definition

### Electronics

- The power in an
__AC circuit__which cannot perform work. It is calculated by the following formula:=*P*·V·sinθ, where*I*is the power in watts,*P*is the current in amperes,*I*is the voltage in volts, and sinθ is the sine of the*V*__angular phase difference__between the current and the voltage. Also called reactive power, wattless power,__volt__-amperes reactive, reactive volt-amperes, or quadrature power.
