A conventional capacitor stores electric energy as static electricity by charge separation in an electric field between two electrode plates. The charge carriers are typically electrons, The amount of charge stored per unit voltage is essentially a function of the size of the plates, the plate material''s properties, the properties of the dielectric material placed between the plates, and the separati…
