Capacitor Function in Alternating Current (AC) Circuits In AC circuits, capacitors exhibit a continuous cycle of charging and discharging due to the alternating nature of the current. The current leads the voltage by 90 degrees in phase, which means that the current reaches its peak one-quarter cycle before the voltage does.
