1. The problem statement, all variables and given/known data [PLAIN]http://img339.imageshack.us/img339/6089/electriccircuits221revi.png [Broken] 2. Relevant equations i = v/R 3. The attempt at a solution My attempt at the solution is all in the red in the diagram above. Apparently the book's answers are 1 V and 2 V and it doesn't say which voltage corresponds with what but I'll assume v1 = 1 V and v2 = 2 V. When I solved for v2 with my equation I got 20 V. Can someone help me out with getting the equations set up so I can solve for the voltages? I drew the loops I used in red. Since there's 2 unknowns, I need at least 2 equations. Problem is, I don't know if my equations are correct.
