Learn MoreIn my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let''s say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite.
Learn MoreResistors dissipate energy but not charge. If two charged plates are connected together, the total charge on the two does not change. If the wires (and plates) have no resistance, then connecting two charged capacitors can result in LC oscillations (depending on voltages and polarities).

Therefore each capacitor will store the same amount of electrical charge on it''s plates regardless of it''s capacitance.. This happens because the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor.
