Hello, I'm trying to write node voltage equations for Node A and B in the following circuit.
My issue is that all of the circuits I've done so far have had obvious "mutual conductance". This circuit however, I'm unsure of. Do they even have a mutual conductance through the unnamed node in the middle?
If there is no mutual conductance I'm thinking the equations will be something like this:
Node A: (0.75 mS)Va = 2mA
Node B: (0.5 mS)Vb = -2mA
So if this were the case Va = 2.67 V and Vb = -4 V
However I feel like there should be some type of mutual conductance here. Maybe something like:
Node A: (0.75 mS)Va - (0.5 mS)Vb = 2mA
Node B: -(0.5 mS)Va + (0.5 mS)Vb = -2mA
This would give Va = 0V and Vb = 4V
Any help would be greatly appreciated, thanks!
