1. The problem statement, all variables and given/known data http://img258.imageshack.us/img258/2152/screenshot01kf5.th.jpg [Broken] 2. Relevant equations KCL KVL V = IR 3. The attempt at a solution I used 4 nodes at the top, one reference node at the bottom. I have it labeled V1, V2, V3, V4, starting from the far left -> right. My nodal equations are: At v1: + 7V At v2: 0 = (v2-v1) / 2 + v2 / 4 + (v2 - v3) / 4 At v3: (v3-v2) / 4 + v3 / 8 + (v3 - v4) / 8 = 0 At v4: 0 = (v4-v3)/ 8 - 1mA so we know V0 is v2-v3 = v0. I'm not sure if this is correct so far.
