Finding current in a RLC circuit using kirchhoff laws

[karlis123]

Homework Statement

Find current flowing through E1 ( find I1).

Homework Equations

I see 6 currents, atleast until the capacitor is charged, what i find confusing are the branches without any resistance and they seem to mess up my equations.

The Attempt at a Solution

1st kirchhoff's law
I1+I5=I2
I3+I6=I1
I6+I5=I4
2nd kirchhoff's law
I2*L-I3*C=E1
I2*L+R1*I5=E2
I3*C+I6*R2=0

In the end i get 2*I5-I6=5 which doesn't solve anything for me so I guess I'm still missing something there.
Its been some time since I've done circuit calculations any help would be apritiated

Are you after a steady-state DC analysis, or is this AC?

If DC, then the inductor and capacitor can be replaced by a short-circuit and an open-circuit, resp.

its a dc circuit right after commutation, the commutator switch is closed and is in series with E2 and R1 (i replaced it with a black line in the picture).
Here i found an example, as i understand i have to calculate the currents in the exact moment when the condenser is being charged.
any help with the equations would help allot.
Thanks in advance

E1 and R1 don't appear to be connected in your circuit. So where is this commutator?

ow my bad! E2 I ment

So to be clear, the circuit looks like this?
