Introduction to capacitors

Capacitance, also known as "capacitance", refers to the amount of free charge stored at a given potential difference, denoted C, and the international unit is Farad (F). Generally speaking, the charge will move by force in the electric field, and when there is a medium between the conductors, it hinders the movement of the charge and makes the charge accumulate on the conductor, resulting in the accumulation and storage of charge, and the amount of stored charge is called capacitance.

Capacitance refers to the ability to hold an electric charge. Any electrostatic field is composed of many capacitors, and there is an electrostatic field there is a capacitor, and the capacitance is described in terms of an electrostatic field. It is generally believed that the isolated conductor forms a capacitance at infinity, and the conductor ground is equivalent to being connected to infinity and connected to the earth as a whole.

Capacitance, or capacitance, is a physical quantity that expresses the ability of a capacitor to hold an electric charge. Capacitor from the physical point of view, it is a static charge storage medium, may charge will exist permanently, this is its characteristics, its use is wide, it is an indispensable electronic component in the field of electronics and electricity. Mainly used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charge and discharge, energy storage, DC isolation and other circuits.
