Explain RC circuit?s charging and discharging?

Answer Posted / kamakshi vairagi

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.
