How Does a Capacitor React to an AC Generator?

What happens when a capacitor is connected across the terminals of an AC generator?

a) The capacitance increases. b) The capacitance decreases. c) The capacitor discharges. d) The frequency of the AC generator increases.

Answer:

When a capacitor is connected to an AC generator, its capacitance does not change. The capacitor charges and discharges in response to the alternating current. The frequency of the AC generator does not affect the capacitance.

When a capacitor is connected across the terminals of an AC generator, the capacitance does not change. The capacitor simply charges and discharges in response to the alternating current from the generator. The frequency of the AC generator does not affect the capacitance of the capacitor.
