In the circuit shown, switch 
has been closed for a long time. At time t = 0 switch 
is closed. At 
, the rate of change of current through the inductor, in amperes per second, is _____________.
Explanation:
When \(S_1\) is open and \(S_2\) is closed, the circuit enters steady state so Inductor will be shorted. The system is shown below,
Current through inductor 
When switch 
is closed at 
then inductor
current at that instant will not change i.e.
It will be 1.5 A; it can be replaced by a current source at that instant.
Let V→ voltage at node A = voltage across inductor
KCL at A,
