What is Capacitor? What is the Use of Capacitor?

Electrolytic Capacitors

A capacitor is an electronic/electric component which stores the charge. In other words, A capacitor is used to store electrons (or electrical energy), and release them whenever desired.

Symbol of Capacitor

Capacitor is Denoted by the following Symbol

Capacitance is a measure of a capacitor’s ability to store charge. It is measured in Farads (F). However, the unit farad being too large, practical capacitors are specified in microfarads (uF), or picofarads (pF).

Capacitor offers low impedance to Alternating Current (AC) and very high impedance to Direct Current (DC) .

In simple words it passes the AC current through it and blocks the DC current, It is also used as a bypass capacitor in some circuits, where it bypass the ac through it without letting the ac to go through the circuit across which it connected. Also, a capacitor forms a tuned circuit in series or parallel with an inductor.
