How Capacitors Work
Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in principle as the second electrode (cathode) …

Let us assume that a capacitor has capacitance C and have electric charge Q and the capacitor is electrically neutral. Where V is the potential difference between the plates. Now if the charge upon the two plates of parallel plate capacitor is different then, V1 will be the potential difference of plate 1 with Q1 be the charge.
