Learn MoreIf by "capacity" you mean the amount of net charge on the plates, then obviously that''s not the same as the capacitance of the capacitor which is the charge divided by the voltage. The capacitance of a capacitor is greater if the work required per unit charge to separate the charge on the plates (i.e., the voltage) is less.
