what does the energy storage of a capacitor relate to

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.

Energy to charge capacitor and stored energy

Aug 20, 2008. Capacitor Charge Energy. In summary, the capacitor stores half the energy supplied by the battery. The power delivered by the battery in charging a capacitor of value ''C'' to voltage ''V'' is C*V^2. The energy stored in the capacitor is (C*V^2)/2. The difference energy i.e. (C*V^2)/2 is dissipated in the resistor.
