However, the basic structure of a capacitor is a constant, which you can see below: Electrodes – these are the two conductive plates that store the energy. Dielectric – determines the capacitance and dielectric strength of the capacitor. Terminal leads – metal wires or pins which connect the capacitor to the circuit. How Does a Capacitor Work?
When voltage is applied, an electric charge accumulates on the plates, allowing for temporary energy storage. Moreover, capacitors can smooth out power fluctuations, helping stabilize circuits by temporarily holding and releasing charge.
