1. The problem statement, all variables and given/known data (a) Determine the current in each branch of the circuit. 2. Relevant equations V=IR Summation of the voltages in a loop = 0 3. The attempt at a solution I have this problem figured out in general, but the only thing confusing me is the current in the middle. What exactly determines the direction of the current in the middle branch? It screwed me over so bad in a similar problem on a test. The current in the middle is pointing down, but why?
