When the battery is removed from the capacitor, the two plates will retain its charge for a certain time. Thus, it acts as a source of electrical energy. Capacitors are designed to operate at a specific maximum voltage. If the external voltage applied to the capacitor exceeds its maximum voltage, the electrons start moving between the plates.
