In the following circuit, the switch has been closed for a very long time prior to t=0 so that the circuit has reached equilibrium. The switch then opens at t=0 as indicated. Determine the inductor current i(t) for both t<0 and t\ge 0 for the circuit below.
In the answers below, use exp() for the exponential, i.e., exp(5) for e^5.
Determine the value of i(t) (in A) at t=0^-.
Enter an expression for i(t) (in A) for t>0.
