WebMar 8, 2016 · Essentially, reactive power is the component of power that has zero time average. For example, consider a load consisting of a resistance R in parallel with an inductance L driven by a source with voltage vS(t) = VScosωt. Clearly, the source current is. iS(t) = VS R cosωt + VS ωLsinωt. Thus, the instantaneous power delivered by the source is. WebJan 28, 2024 · The AC resistive value of a capacitor called impedance, ( Z ) is related to frequency with the reactive value of a capacitor called “capacitive reactance”, XC.
