Electric Field Strength:Electric field strength refers to the force experienced by a unit positive charge placed in an electric field. It quantifies how strong or weak an electric field is at any given point.
Capacitance:Capacitance is a measure of how much charge a capacitor can store for a given voltage difference across its plates.
Dielectric Material: A dielectric material is an insulating substance inserted between the plates of a capacitor to increase its capacitance by reducing the electric field strength.
