Capacitor Basics: How do Capacitors Work? | CircuitBread
A capacitor is an electrical energy storage device made up of two plates that are as close to each other as possible without touching, which store energy in an electric field. They are usually two-terminal devices and their symbol represents the idea of two plates held closely together. Schematic Symbol of a Capacitor.
