Reactive power in AC circuit - Electrical Engineering Stack …

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. If the load is purely resistive, the two quantities reverse their polarity at the same time. At every instant the product of voltage and current is positive or zero, the result being that the direction of energy flow does not reverse. In th… WebMar 12, 2024 · Reactive power Q L = 230 × 10 × 0.714 = 1642.52 VAR. When the capacitor is added in parallel to the load it supplies the reactive power (Q C) to the load. So the total reactive power supplied by the source (Q) to load will decreases, it can be shown as. Q = Q L - Q C. But the total active power supplied by the source to the load remains same.
