1. The problem statement, all variables and given/known data hi guys, i'm having trouble applying Kirchhoff's laws to determine the equivalent resistance of this symmetrical array of resistors (see attachment); i think there is a quick trick, using 4 current loops, but i can't remember it... nor find relevant documentation – this is not homework, i'm practicing for a test and never took this class... A shame, since i already graduated!– 2. Relevant equations Kirchhoff's laws. 3. The attempt at a solution Totally intuitive: R.
