Capacitance is used to characterize the energy storage capacity of electronic components under a certain potential difference. When a medium is filled between conductors, the charge moves under the activation of an electric field. The medium limits movement, so charges accumulate and are stored in the drive. A capacitor is an element that stores electricity and electric energy (electric potential energy). Two conductors close to each other and sandwiched with a layer of non-conductive insulating medium constitute a capacitor. When a voltage is applied between the two plates of a capacitor, an electric charge is stored. Capacitors play an important role in tuning, bypass, coupling, filtering and other circuits.
