Helping setting up Nodal Equations.... 1. The problem statement, all variables and given/known data I need to find the node voltages at N1 and N2. See attachment for circuit. 3. The attempt at a solution I think I need to setup KCL at each node. At Node 1, I got this: (v1-v2)/12 - (v3-v2)/20 - (v2-0)/40 =0 v1 is the source voltage, and v3 is the voltage at node 2. Is this correct thus far?
