Ans: During the process of charging the capacitor, the current flows towards the positive plate (and positive charge gets added to that plate) and away from the negative plate. While during the discharging of the capacitor, current flows away from the positive and towards the negative plate, in the opposite direction.

Charging and Discharging of a Capacitor | RC Circuit
When connected to a battery, the capacitor stores electrostatic energy. This energy is in the form of charge on its plates which raises the potential difference between the plates. When required, this capacitor can release this stored energy and gets discharged. Charging. A capacitor is charged by connecting it to a voltage source and a resistor.

9. CHARGING A CAPACITOR At first, it is easy to store charge in the capacitor. As more charge is stored on the plates of the capacitor, it becomes increasingly difficult to place additional charge on the plates. Coulombic repulsion from the charge already on the plates creates an opposing force to limit the addition of more charge on the plates. Voltage …
