Working Principle

The working principle of a film capacitor is based on the fact that the dielectric material (film) has a different amount of electrical charge than the metal plates, known as the electrodes. This creates an electrical field between the two, which stores energy in the form of electrical charge. When a current is applied to the capacitor, the electric field generated by the dielectric material (film) attracts the opposite electric charge from the metal plates. This creates an electrical charge stored on the capacitor, and the capacitor acts as a circuit element that is capable of storing and transmitting electrical energy. The capacitance of the device is determined by the amount of charge stored per unit area, which is a function of the thickness and dielectric constant of the material. The device has a fixed capacitance and is often used in AC circuits to reduce current peaks by providing a smooth, constant outlet current.
