2. Homework Equations
V=IR
The Attempt at a Solution
Basically from reversing the polarity of the cell and looking at a mirror image of the circuit i got the following relationships. First I(9)=0 then I(1)=-I(4) I(5)=-I(6) I(7)=-I(8). I believe i can also get these from a symmetry argument. From there I went ahead and wrote down equations for the currents at points A,B,C and O. I inserted the current through the cell to be I(10) and after a few equations i got I(10)=0 and so the equivalent resistance to be infinite ?? I made a mistake somewhere. Is it just a mistake during my calculations or is my approach wrong? I believe the error might be I(9)=0 but I'm not sure
