Homework Equations
V=IR
Kirchoffs Current Law
The Attempt at a Solution
I picked the middle node (the one surrounded by 3 resistors) as my reference. V1 and V2 are my other two nodes.
I'm also assuming that V1>V2, V1<reference
Using Kirchoffs Current Law:
(Node 1)
-(0-V1)/6 +6 + (V1-V2)/9 -4 -(0-V1)/2=0
(Node 2)
4 + V2/4 - 6 -(V1-V2)/9 = 0
(I_0 current)
I_0 = (0-V1)/6
Of course, I keep getting the wrong answer and just can't solve this problem
