A circuit draws 330 W from a 110V, 60 Hz AC line. The power factor is 0.6 and the current lags the voltage. The capacitance of a series capacitor that will result in a power factor of unity is equal to
View answer and explanation
Correct option: B
54μF
Option B (54μF) is correct because the capacitance is calculated to cancel out the inductive reactance and achieve a unity power factor.
