In this article, you will learn about charging and discharging a capacitor. When a voltage is applied on a capacitor it puts a charge in the capacitor. This charge gets accumulated between the metal plates of the capacitor. The accumulation of charge results in a buildup of potential difference across the capacitor plates.
In both charging and discharging processes of a capacitor through a resistance, the current always decreases from its maximum value to zero. What is discharging of a capacitor? The discharging of a capacitor is the process through which stored charge within the capacitor is released.
Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero. The following graphs summarise capacitor charge. The potential difference and charge graphs look the same because they are proportional.
capacitor is equal to the potential difference across the battery.

harges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across th capacitor is equal to the potential difference across the battery.

Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then
