var

- The
__SI____unit__for reactive power, which is the power in an__AC circuit__that cannot perform work. It is calculated by the following formula:=*P*, where*I·V·sinθ*is the reactive 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. It is an acronym for volt-amperes reactive. - acronym for volt-amperes reactive (written as
