The greater the difference of electrons on opposing plates of a capacitor, the greater the field flux, and the greater the "charge" of energy the capacitor will store. Because capacitors store the potential energy of accumulated electrons in the form of an electric field, they behave quite differently than resistors (which simply dissipate energy in the …
