Why exactly do capacitors charge and discharge exponentially?
When a capacitor discharges through a simple resistor, the current is proportional to the voltage (Ohm''s law). That current means a decreasing charge in the capacitor, so a decreasing voltage. Which makes that the current is smaller. One could write this up as a differential equation, but that is calculus.

6 FAQs about [Current image when capacitor is charging and discharging]
What are charge and discharge graphs for capacitors?
Charge and discharge voltage and current graphs for capacitors. Capacitor charge and discharge graphs are exponential curves. in the above circuit it would be able to store more charge. As a result, it would take longer to charge up to the supply voltage during charging and longer to lose all its charge when discharging.
Why do capacitor charge graphs look the same?
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.
What happens when a capacitor is discharged?
When a capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the capacitor is fully discharged as there is no charge stored across it. The rate of decrease of the potential difference and the charge will again be proportional to the value of the current.
What happens when a capacitor is charged?
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 the start, the current will be at its highest but will gradually decrease to zero.
How does a capacitor charge through a battery?

When a capacitor is full of charge the current is highest?
The size of the current is always at a maximum immediately after the switch is closed in the charging or discharging circuit, because the charging current will be highest when the capacitor is empty of charge, and the discharging current will be highest when the capacitor is full of charge. This is shown in the graphs in Figure 2. 2.
