6.1.2: Capacitance and Capacitors

A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as

What is Film Capacitor & What is it used for?

The dielectric used in this sort of capacitor can be any form of film. There is a ''direct electrical connection'' establishment with the electrodes that are present on both windings in the modern form of film capacitor. This reduces the current''s route to the electrode to a minimum. Film capacitor is relatively simple to analyze and build
