In the circuit shown, `S_(2)` is closed first and is kept closed for a long time. Now `S_(1)` is closed. Just after that instant the current through `S_(1)`is

In the circuits shows in S_(1) and S_(2) are switches. S_(2) remains closed for a long time and S_(1) is opened. Now S_(1) is also closed. Just after S_(1) is closed, find the potential difference (V) across R and di//dt (with sign) in L .

In the given circuit switch S_(2) is Kept closed and S_(1) is kept open for a very long time such that the system is in steady- state . Now S_(1) is also slosed keeping S_(2) closed. Current passing through R just after S_(1) is closed , is :
