The charge and discharge of a capacitor
When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. The rate at which a capacitor can be charged or discharged depends on: (a) the capacitance of the capacitor) and

21.6: DC Circuits Containing Resistors and Capacitors
The equation for voltage versus time when charging a capacitor (C) through a resistor (R), derived using calculus, is [V = emf(1 - e^{-t/RC})(charging),] where (V) is the voltage across the capacitor, emf is equal to the emf of the DC voltage source, and the exponential e = 2.718 … is the base of the natural logarithm.
Capacitor in Electronics
Discharge: If a path is available for the charges to move (for instance, by connecting a resistor across the capacitor), the capacitor starts discharging. The discharge process results in a current flowing in the circuit. The voltage across the capacitor decreases over time until it reaches zero, at which point the capacitor is fully …
