Question

In the circuit shown in figure,the initial current through the inductor at $$t=0$$ is $$I_0$$.After a time $$t=\dfrac{L}{R}$$, the switch is quickly shifted to position 2.Plot graph showing the variation of current with time.

Solution

a) Shifting the position of switch increases the resistance of the circuit. This decreases the value of time constant ,Consequently , the rate of decreases of current increases. The variation of current with time is shown in figure.PhysicsNCERTStandard XII
