The term, 'leading' power factor, describes a circuit in which the
A) load current leads the supply voltage.
B) load current lags the supply voltage.
C) load current is in phase with the supply current.

Question

Quizplus · Accepted Answer

In a leading power factor circuit, the load current leads the supply voltage, meaning that the current waveform reaches its peak before the voltage waveform. This can occur when the circuit contains capacitors, which cause the current to advance in phase. A lagging power factor circuit, on the other hand, has a load current that lags behind the supply voltage, occurring when the circuit contains inductors. A circuit with unity power factor has a load current that is in phase with the supply voltage.
