There are two types of capacitor, non-polarized and polarized. The non-polarized capacitor holds equal amounts of charge in each of its two plates so that a difference in charge is only achieved when electrical current from a power supply transfers electrons from one plate to another to cause a potential difference, storing electrical energy in the process. When the power supply is cut off and a load is connected to the non-polarized capacitor, the electrons flow from the charged plate, to the load, and back to the other plate until both plates hold an equal amount of charge and the capacitor once again becomes neutral. But in the case of polarized capacitors where one plate has excess amounts of charge compared to the other plate, will the plate with excess amounts of charge not spontaneously transfer electrons to the other plate if connected to a load or shorted, even without the aid of a power supply because there is already an imbalance of electric charge? And will this transfer of electrons not balance out the charges on the two plates and cause the polarized capacitor to become non-polarized?
