In 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.
