Storage charge of film capacitors

Film capacitor can store charge and has the function of blocking DC. After storing charges on Film capacitor, the capacitor two plates are separated by insulating medium, though there are voltages at both ends of the capacitor. But the charge can not pass through the electrode, so it has the function of blocking DC. If the two electrodes of the charged film capacitor are connected by a wire, at the moment of connection, the positive and negative charge on the capacitor plate will be neutralized through the wire. This is the discharge of the capacitor. The discharge process of a capacitor is a process of energy release. It will work in the discharge circuit and convert electrical energy into other forms of energy.
