Why are capacitors useful in power factor correction?
What will be an ideal response?
It is common practice in many industrial installations to use banks of capacitors for power factor correction. A capacitor is a device that has a leading current and, therefore, a leading power factor. When capacitors are connected in a circuit with inductors, the leading VARs of the capacitors act to cancel the lagging VARs of the inductors. In this way, power factor can be corrected.
