A)a capacitor in series with an ac generator
B)an inductor in series with an ac generator

D)a capacitor and resistor in series with an ac generator
E)a capacitor and inductor in series with an ac generator

Question

Quizplus · Accepted Answer

In a circuit with a capacitor and resistor in series with an AC generator, the current is not in phase with the voltage, resulting in a non-zero power factor. This is because the capacitor will store energy during part of the AC cycle and release it during another part, leading to a phase shift.
