Charging a Capacitor: The voltage across the capacitor is not instantaneously equal to that of the
voltage across the battery when the switch is closed. The voltage on the capacitor
builds up as more and more charges flows onto the capacitor until the battery is
no longer able to "push" any more charge onto the capacitor, at which point the
capacitor becomes fully charged.The initial flow of charges from the battery to
the capacitor means that there is a current flowing through the system until the
capacitor is charged. This current flow decays exponentially from some initial
value to zero.
DisCharging a Capacitor: Switch remains open and voltage across capaciotr decreses untill it reaches zero.
