About Capacitor

A capacitor is an electronic component that can store and release electricity. It has a structure in which an insulator is sandwiched between two metal plates that face each other, and when a voltage is applied, electric charges move. stored in a metal plate. This allows the capacitor to act like a charged battery. In terms of storing and discharging electricity, they are often confused with batteries, but while batteries basically convert electrical energy through chemical reactions, capacitors store electric charges directly without such a conversion process. It is characterized by being able to repeat extremely high-speed charging and discharging. Capacitors can be built into power supply circuits and repeatedly charged and discharged to buffer sudden voltage changes and provide stable voltage application. Capacitors also have the characteristic of allowing high-frequency alternating currents to pass through easily, and by using this, they also play a role as filters, such as removing noise and cutting DC components.
