Hi everyone I am trying to find the current of a circuit using linear algebra. So far, I know that there are 6 loops, one on each side of the cube. However, I am not sure about how many equations I have to come up with to construct a matrix and thus solving the problem. The questions is to find the currents that are going through EACH resistor, and the DIRECTION that they are going in. There should be a total of 12 arrows indicating the directions of the currents, 1 on each side. ANY help/hint/suggestion is GREATLY appreciated.
