Hello
In this question, I have the voltage between A and B and I need to find Vin.
How do I do that?
I tried setting the ground at B, and I called V1 the node above A and V2 the node below A.
I did a node voltage:
V1/5 + (V1-VAB)/4 = 0
and same for V2
then I tried Vin = V1 - V2 but I did not reach the desired value.
Can somebody help me?
