Homework Statement
Use the node voltage method to find v in the circuit shown.
(picture of circuit attached)
Homework Equations
The Attempt at a Solution
v1 + (v1  v2)/8 = 4.5
(v2  v1)/8 + (v2)/12 + (v2  30)/4 = 0
Solving for v1 and v2 I get:
v1 = 6 V
v2 = 18 V
I got the voltage at node 1 and 2 (along the top of the circuit), but I'm puzzled as to how to get v? Thanks for your help.
