Capacitor definition

What is capacitor ?

A capacitor is an electronic component that can store charge and energy. It consists of two conductive plates (called electrodes) and an insulating material (called a dielectric or dielectric) sandwiched between them. The main parameters of a capacitor include capacitance (in farads, usually expressed in microfarads μF or nanofarads nF), withstand voltage (the maximum voltage that a capacitor can withstand), temperature coefficient, equivalent series resistance (ESR), etc.

The main functions of capacitors in circuits include:

Energy storage: Capacitors can store electrical energy and release it when needed. This feature is very important in power supply systems.

Filtering: Capacitors can be used to filter out noise in signals. In power supply circuits, capacitors are often used to smooth voltage fluctuations.

Coupling: In an AC circuit, capacitors can be used to block the DC component and allow only the AC signal to pass through, which is called signal coupling.

Tuning: In radio and communication equipment, capacitors and inductors are used together to tune the circuit to select a specific frequency.

Capacitors have a wide range of applications, including energy storage, decoupling, filtering, timing circuits, motor starting, power factor correction, signal coupling,etc.
