The circuit is in DC steady state before switch flips at t=0. I need to find vL(0-) , iL(0-) , iL(t) , vL(t) for t>0

 

To find vL(0-) and iL(0-) assume that the inductor is a short circuit.

To find the rest replace the battery with a short circuit and find the equivalent parallel resistance of the inductor. Then use the exponential equations to find the current and voltage agianst time.
