- 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*V*__sine__of the__angular phase difference__between the current and the voltage. Its abbreviation is VAR. Also called reactive volt-amperes, reactive power, idle power, wattless power, or quadrature power. - acronym VAR
