3. The Attempt at a Solution [/B]

I will upload the picture of my work here an then explain what i did.

I labeled the steps so you can refer to them in your comments. I will also rewrite some of it here:

First i wanted to find the current through the branch with the switch when it is closed and i did that in the following way. I changed the circuit diagram into the Δ circuit as you see in the picture. Then using simple steps i found the current through the branch. But I'm clueless about what do i do now. Why did i need that current in the first place?

Could you give me a clue that is of the form which theorem to use and why. Thanks
