Capacitance, also known as capacitance, is a physical quantity that measures the amount of free charge stored at a given potential difference, usually represented by the symbol C, and its international unit is Farad (F). The basic composition of a capacitor includes two metal plates and a dielectric material, which allows the capacitor to store charges.

The working principle of capacitors is based on their structural characteristics: when there is a dielectric between two conductor plates, charges will accumulate on these two conductor plates. When these two conductive plates are connected to a power source, they attract opposite charges, forming an electric field between them. During this process, the capacitor impedes the movement of charges through its dielectric, but allows for the establishment of voltage, thereby achieving charge storage.

The main functions of capacitors include charging and discharging, bypass and decoupling, energy storage and coupling, etc. These functions make capacitors widely used in electronic circuits, such as filtering, energy storage, and signal processing. The performance of a capacitor can be described by several key parameters, including electrode area, electrode spacing, and the induced charge of the dielectric material used. These parameters directly affect the capacitance value of the capacitor, that is, how much charge the capacitor can store. Capacitors are an important electronic component that plays a crucial role in various electronic systems by implementing specific structural designs to store and manage charges.
