Homework Equations
KCL set ups
The Attempt at a Solution
I am having trouble setting up the KCL equations
The 30V voltage source on the left with the resistor is messing me up, how do I incorporate that?
Do I just do 30/15 and assume a 2A current source is going into node A?
Here are my equations:
VD = reference node = 0 V
KCL @ Node B
(VB-VA)/25 + (VB-VC)/50 - 1 + 4 = 0
KCL @ Node C
(VC-VD)/50 + (VC-VB)/50 + 1 = 0
KCL @ Node A?
(VA-VB)/25 + (VA-VD)/31.25 - 4 + ?? = 0
