WebMay 27, 2016 · The power factor is defined as the ratio of the active power (P) and volt-amperes. The active power is the real power which is assumed in an AC circuit, whereas volt-amperes is the apparent power which is produced in the circuit when the waves of voltage or current are not in phase. WebThus, our example circuit started out with a power factor of 0.705 lagging, and was corrected to a power factor of 0.999 lagging. REVIEW: Poor power factor in an AC circuit may be “corrected”, or re-established at a value close to 1, by adding a parallel reactance opposite the effect of the load's reactance.
