Learn MoreAt the same time, the series capacitor would allow AC current to pass. This configuration is often called a coupling capacitor. If the capacitor is a parallel path to ground, then the capacitor can effectively act as a charge reservoir to provide current when the voltage of the DC dips. This is typically called a filter capacitor.
