a voltage source, resistance,capacitor and a switch are in series in circuit. Initially the switch is open.At t=0 the switch is closed.I have to find the transient response of the circuit.
so first as the switch is open initially so voltage across capacitor is zero.
at t=0 switch is closed. applying kvl,
Ri(t)+vc(t)=V
can any one suggest how to proceed further

when the switch closes the current will be at its maximum limitted by the resistance. as the capscitor charges up, the current decreases to zero, following the rc timeconstant formula.
