Answer / Gaurav Kumar Dinkar

Reactive power (Q) is a measure of the electrical energy that fluctuates between the voltage and current waveforms in an AC circuit, specifically the component perpendicular to real power (active power). Reactive power is essential for maintaining the stability of an electrical system. It allows the reactive components in the circuit, such as inductors and capacitors, to store energy during one part of the cycle and release it during another part, thereby facilitating current flow.
