Reactive power phasor diagram

Reactive power does not do any work, so it is represented as the imaginary axis of the vector diagram. Active power does do work, so it is the real axis. The unit for power is the watt (symbol: W). Apparent power is often expressed in volt-amperes (VA) since it is the product of RMS voltage and RMS current. See more In an electric circuit, instantaneous power is the time rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals … See more The formula for complex power (units: VA) in phasor form is: $${\displaystyle S=VI^{*}= S \angle \varphi }$$, where V denotes … See more In a direct current circuit, the power flowing to the load is proportional to the product of the current through the load and the potential drop across the load. Energy flows in one … See more A perfect resistor stores no energy; so current and voltage are in phase. Therefore, there is no reactive power and See more In a simple alternating current (AC) circuit consisting of a source and a linear time-invariant load, both the current and voltage are sinusoidal at the same frequency.
