batteries
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.

Capacitor vs. Battery: What''s the Difference?
We don''t use capacitors as batteries because they can''t store as much energy as batteries, and they also can only handle current in one direction. Additionally, capacitors are usually much smaller in size and weight than batteries, which means they are not suitable for applications that require a lot of energy or that need to be charged or …
