Answer 1

Correct choice is (a) Leading, Lagging The best explanation: A Leading power factor means that the current in the circuit leads the applied voltage. This condition occurs in capacitive circuits. On the other hand, a lagging power factor indicates that the current lags the voltage and this condition happens in an inductive circuit.
