Some dielectric constants of materials used in manufactured capacitors are provided in the following table: Moving charge from one initially-neutral capacitor plate to the other is called charging the capacitor. When you charge a capacitor, you are storing energy in that capacitor.
They have two conductors separated by a dielectric layer. The dielectric material is an insulator with the ability to polarize easily. When the two conductors have a voltage difference, the electric field creates an electric charge within the capacitor, creating stored electric energy.
U is the electric potential energy (in J) stored in the capacitor’s electric field.

Dielectrics are materials with very high electrical resistivity, making them excellent insulators.
A thin dielectric is ideal for a component’s total capacitance, dependent on the following equation: C = εA/d Here C is the total capacitance, ε is the permittivity, A is the separated area between electrodes, and d is the distance between these two areas.
