A lagging power factor denotes that on the phasor diagram, the current lags (is behind) the voltage, and a leading power factor denotes that the current leads (is ahead) the voltage. For inductive loads (e.g. induction motors, coils, lamps), the current lags behind the voltage, thus having a lagging power factor.

WebIf the input is sinusoidal and the circuit makes no distortion, the output is also sinusoidal, but often its timing is in front (=leading) or behind (=lagging) the timing of the input voltage and the difference does not change as long as the frequency doesn't change. The lead or lag is usually expressed as degrees and called "phase shift". WebThis results in a voltage wave that is 90° out of phase with the current wave. Looking at the graph, the voltage wave seems to have a “head start” on the current wave; the voltage “leads” the current and the current “lags” behind the voltage.
