1. The problem statement, all variables and given/known data I have a network of resistors in a box-formation. There is 1 resistor of equal resistance in between every corner of the box, so 12 in total. 2. Relevant equations In series R = r1 + r2 + ... ri In parallel, 1/R = 1/r1 + 1/r2 + ... 1/ri 3. The attempt at a solution I can't really draw a 2D analogous network due to the connections. I know kirchhof's rules must be applied somehow... that no current will flow between two points of equal potential difference, but not sure where that would be.
