Question

In the circuit shown, the switch S 1 ​ is closed at time t = 0 and the switch S 2 ​ is kept open. At some later time ( t 0 ​ ) , the switch S 1 ​ is opened and S 2 ​ is closed. the behaviour of the current I as a function of time ' t ' is given by:

The current will grow for the time t = 0 to t = t 0 ​ and after that decay of current takes place. Growth and decay of current is of exponential nature i = i 0 ​ ( 1 − e − t / τ ) → during growth i = i m a x ​ e − t / τ → during decay
