WebJan 26, 2024 · Reactive power is the resultant power in watts of an AC circuit when the current waveform is out of phase with the waveform of the voltage, usually by 90 degrees if the load is purely reactive, and is the result of either capacitive or inductive loads. Only when current is in phase with voltage is there actual work done, such as in resistive ... WebReactive power represents an energy exchange between the power source and the reactive loads where no net power is gained or lost. The net average reactive power is zero. Reactive power is stored in and discharged by …

Web(a) The three different types of power in AC circuits are as follows: • S = apparent power, measured in Volt-Amps (VA) • P = true power, measured in Watts (W) • Q = reactive power, measured in Volt-Amps reactive (VAR) Explain the names of each of these power types. Why are they called “apparent,” “true,” and “reactive”? WebThe Complex sum of Real Power (P) and Reactive Power (Q) is known as Complex Power which can be expressed like S = P+jQ and measured in terms of Volt Amps Reactive (generally in kVAR). It may also be expressed as S=VI* where “ I* ” is the conjugate of the complex current I .
