Electric field in a parallel plate capacitor

A capacitor is a device used in electric and electronic circuits to store electrical energy as an electric potential difference (or an electric field) consists of two electrical conductors (called plates), typically plates, cylinder or sheets, separated by an insulating layer (a void or a dielectric material).A dielectric material is a material that does not allow current to …
