A capacitor is a device that stores electrical charge. The simplest capacitor is the parallel plates capacitor, which holds two opposite charges that create a uniform electric field between the plates. Therefore, the energy in a capacitor comes from the potential difference between the charges on its plates.
From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV. That is, all the work done on the …
Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q Q and voltage V V on the capacitor. We must be careful when applying the equation for electrical potential energy Δ PE = q Δ V Δ PE = q Δ V to a capacitor.
