This is a very small version of the problem I'm trying to solve. I can use PSpice to calculate the node voltages if I know the resistor values but I need to find the reverse.
In other words, I know all of the node voltages and even the current flowing out of the voltage source.
I've performed a node analysis but that only provides the same number of equations as the number of nodes, and there are more resistors than nodes.
The question is, whether it's actually possible to solve this problem and if so how?
I realise that this is going to result in as many simultaneous equations as the the number of resistors. That could end up running into thousands, but I understand that there are ways of solving those using matrices.
Does anyone have a handle on this?
Here's a link to the kind of circuit matrix I'm using
