1. The problem statement, all variables and given/known data http://edugen.wileyplus.com/edugen/courses/crs4797/dorf1571/dorf1571c04/image_n/n04f090.gif Determine values of the node voltages, v1, v2 v3, v4, and v5 in the circuit shown. 3. The attempt at a solution Doing nodal analysis I came up with the following four equations but I'm missing one for v5. (v1 - v5)/2Ω + (v1 - v3)/5Ω + (v2 - v4)/4 = 0 v2 - v1 = -8v v3/8Ω + (v3 - v2)/10Ω + (v3 - v1)/5 = 0 v4 - v3 = 16 Is there an easy way to find v5 or do I have to attempt mesh current analysis to get v5?
