WhatsAppIt is continuously depositing charge on the plates of the capacitor at a rate of (I), which is equivalent to (Q/t). As long as the current is present, feeding the capacitor, the voltage across the capacitor will continue to rise. A good analogy is if we had a pipe pouring water into a tank, with the tank''s level continuing to rise. ...
