Find total resistance between A and B
The Attempt at a Solution
Well, first I tried using Kirchhoff's Laws to find the resistance, but that ended up being a total mess so here's what I tried, not sure if it is correct.
Can the (R+R) and 2R branch on the left, be combined to 1R? I was thinking that this would be correct because the same amount current should be on each side of A.
If that is correct, then I can simply do R + 2R (right side resistance in parallel) = 3R. (I think)
Is this correct, or do I need to use Kirchoff's laws to solve?
