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.

A continuity tester with diode test is integrated in many multimeter models. This can also be used to test a capacitor. In this way, however, it can only be determined whether a capacitor is being charged. The current from the measuring device first flows into the capacitor until it is fully charged. The resistance measurement can then be ...
