I'm asked to find an equivalent resistance and the current through each branch of the following circuits. (r is a fixed arbitrary value for all resistors in the circuits)(adsbygoogle = window.adsbygoogle || []).push({});

2. Relevant equations

V=IR

Sum of I at a node = 0

Sum of V about a closed loop = 0

3. The attempt at a solution

I've been playing with both KVL and KCL equations trying get a working answer, but none of my attempts seem to be anything but cyclically finding me zero. My problem is how I consider the input current. Is it right to make the assumption that I essentially have a battery there which has the value of ε = i*R_equivalent. The circuits cannot be broken down in terms of parallel or series from what I've seen.
