I have an electric circuit of which the structure is known but the value of the single components (all resistors) is not. I can measure experimentally the resistance between some points of my circuit. Is there a way to obtain, in a faster way than doing it by hand, analytical expression for the measured resistances in terms of the circuit resistors, so that I can try to solve a system to obtain them?

In the circuit I'm analyzing there are 7 resistors and I can measure 10+ resistances, some of which are redundant.

    $\begingroup$ Perhaps, this question should be asked on the EE or physics stackexchange site. It does not seem to involve Mathematica software. $\endgroup$ – bbgodfrey Aug 3 '17 at 19:31
  • $\begingroup$ It is not really a physics question, I know how to do it with paper and pen. I was wondering if Mathematica can speed up the process! $\endgroup$ – Matteo Pompili Aug 3 '17 at 19:32

    $\begingroup$ If you can write all the equations governing the circuit, and provide values of enough of the electrical quantities, Mathematica can solve for the rest by matrix inversion. $\endgroup$ – bbgodfrey Aug 3 '17 at 19:35
  • $\begingroup$ I second bbgodfrey's suggestion. Unless there is something tricky going on, it seems to me that the core (if not the entirety) of the question is to solve a system of equations. $\endgroup$ – Kellen Myers Aug 4 '17 at 2:54
