Capacitors A capacitor is a passive element designed to store energy in its electric eld. When a voltage source v is connected to the capacitor, the amount of charge stored, represented by q, is directly proportional to v, i.e., q(t) = Cv(t) where C, the constant of proportionality, is known as the capacitance of the capacitor.

I have never clearly understood what a capacitor does... I never understood its purpose in a circuit. How to understand it. An interesting paradox is that, in order to understand circuits, it is more important to have an idea of how their constituent components behave than of their internal structure and physical nature.
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
