Solution Summary

It shows how to find the inductor current after the switch closes. The solution is detailed and was rated '5/5' by the student who posted the question originally.

Solution Preview

Please see the attached file.

When the switch is open, at the steady state, the inductor is treated as a short circuit, so the current at t = 0- is

Therefore, it gives the initial current when the ...
