Reactive power phasor diagram

WebA simple phasor diagram with a two dimensional Cartesian coordinate system and phasors can be used to visualize leading and lagging current at a fixed moment in time. In the real … 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.
