WebSep 2, 2024 · We define the reactive power to be positive when it is absorbed (as in a lagging power factor circuit).. a. Pure capacitance element – For a pure capacitance element, P=0 and I leads V by 90° so that complex power is:. S = jQ = (V ∠0°) (I ∠90°) S = V×I ∠−90° S = −jV×I. Thus the capacitance element generates reactive power. WebJun 29, 2024 · The key difference between the leading power factor and the lagging power factor is that, for the leading power factor, the current is advanced in phase … WebPower factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA).
