Working Principle
Film capacitors are made up of two metallic electrodes that are separated by a thin layer of dielectric material. When a potential difference is applied between the two electrodes, the dielectric material polarizes, allowing electrical current to flow through the capacitor. This process produces an electrostatic field stored between the electrodes, and it is this stored field that creates the electrical capacitance. Furthermore, when the applied voltage is reversed, the polarization of the dielectric material also reverses, releasing the stored electrical energy. This reversed energy is known as the leakage current.
