The circuit is in steady state for t < 0. I need to find the voltage across the inductor ∀t.

I'm trying to solve this circuit using Norton's (tried Thevenin too) theorem , but I can't find the current jcc that flows through the short-circuited inductor.

I've determined the equivalent resistance at the inductor's terminals, by turning off the independent sources

Then, I've applied the superposition theorem to find the current jcc.

First, I've turned off the voltage source e(t), so it is short-circuited.

This is where I'm having trouble. How do I find jcc? With the voltage source and the inductor short circuited the resistor R2 and R4 are in parallel, this parallel is in series with the resistor R1 which is in parallel with R3. Is jcc equal j(t)?

I appreciate any help
