Active Power & Reactive power

Let us consider a single phase power circuit in which current lags behind the voltage by an angle φ.Let the instantaneous electric potential difference v = Vm.sinωtThen the instantaneous current can be expressed as i = Im. sin(ωt – φ).Where, Vm and Im are the maximum values of sinusoidally varying electric potential difference and current …
