As charging of capictor graph is exponential.

When capacitor charging current increases exponentially and also when capacitor discharging current decreases exponentially.

Since vc=vin(1-e^-(t/rc)),

Capacitors rate of charge is considered exponential.

Why capacitor charge and discharge exponential ?

When a.c supply is given voltage across capacitor is IZ where i = cdv/dt where v = vmcoswt finally after derivation we got an exponential signal.

During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply.
