Capacitor is a basic storage device to store electrical charges and release it as it is required by the circuit. Capacitors are widely used in electronic circuits to perform variety of tasks, such as smoothing, filtering, bypassing etc. One type of capacitor may not be suitable for all applications. Different types of capacitors are used for different functions such as DC blocking, Filtering, By Passing, Coupling, and Decoupling and as a Snubber. They are used in applications such as Tuned circuits, signal processing, etc…
