Because of the above functions, capacitors perform two major functions in electronic circuits: ① In DC current, electricity is stored and discharged. Capacitors not only store electric charge but also discharge it, so the capacitor itself becomes the power source. A simple example is the strobe light emission of a camera.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
As we will see in this capacitor tutorial, Capacitors are energy storage devices which have the ability to store an electrical charge across its plates. Thus capacitors store energy as a result of their ability to store charge and an ideal capacitor would not loose its stored energy.
We find capacitors in televisions, computers, and all electronic circuits. A capacitor is an electronic device that stores electric charge or electricity when voltage is applied and releases stored electric charge whenever required. Capacitor acts as a small battery that charges and discharges rapidly.
The main function of a capacitor is to store electric energy in an electric field and release this energy to the circuit as and when required. It also allows to pass only AC Current and NOT DC Current. The formula for total capacitance in a parallel circuit is: CT=C1+C2…+Cn.
Capacitors play an even more important role as filters to divert spurious electric signals and thereby prevent damage to sensitive components and circuits caused by electric surges.

In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effe…
