Hi,
I was wondering could anyone help me understanding this circuit.

Im looking for the initial states of the capacitor and inductor at steady state. (t<0)
As far as I know, to analyse this I have to replace the capacitor with an open circuit and the inductor with a short circuit. Doing this yields 10v across the capacitor and 1 amp through the inductor.

Am I doing this right? Does R3 (the 30Ω resistor) have any effect on the circuit in steady state?

Any help is appreciated...

You appear to be off to a proper start.

R3 does not participate in the steady-state conditions since the capacitor will have been fully charged to the 10 Vdc consistent with the voltage at the intersection of the two 10 ohm resistors.
