When a capacitor charges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear. At.

During capacitor discharging, both the voltage and current exponentially decay to zero. In contrast, during capacitor charging, charge is accumulated on the capacitor. Capacitor charging and discharging are related to the charge. Capacitor charging means the accumulation of charge over the capacitor, while capacitor discharging means the reduction of charge from the capacitor plates.
The discharge of a capacitor is exponential, the rate at which charge decreases is proportional to the amount of charge which is left. Like with radioactive decay and half life, the time constant will be the same for any point on the graph: Each time the charge on the capacitor is reduced by 37%, it takes the same amount of time.
The process of charging and discharging a capacitor is governed by ohm’s law, voltage law, and the basic definition of capacitance. When considering a circuit with a capacitor C, voltage source V, and a toggle switch, the transient response refers to the behavior of the capacitor as it charges or discharges. Initially, the capacitor is discharged and the switch is open.
If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across it reaches that of the supply voltage. The time required for the capacitor to be fully charge is equivalent to about 5 time constants or 5T.
The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).
