Examples of 'reactive current' in a sentence
Meaning of "reactive current"
Reactive current: Reactive current is the flow of alternating current that leads or lags behind the voltage waveform in an AC circuit. It occurs in reactive components like capacitors and inductors. Reactive current does not perform work directly but is essential for maintaining the electromagnetic field in the circuit
