1. The problem statement, all variables and given/known data So, imagine that there are two wires stretched across 2 electrodes crossing over eachother, dividing each wire into two pieces at a junction, j. Each wire is connected to two electrodes, one at each end. The pieces have resistances R1, R2, R3, and R4 and the resistance at the junction is Rj. 2. Relevant equations Series: Rtot = R1 + R2 Parallel 1/Rtot = 1/R1 + 1/R2 3. The attempt at a solution Circuit Diagram(attached) I tried saying R1, Rj, and R4 are in series and are parallel to R2 and R3 and for (1/R2 + 1/(R1+RJ + R4) + 1/R3)^-1, but then you could say that R3, RJ, and R2 are in series and parallel to R1 and R4, but (1/R1 + 1/(R2 + Rj + R3) + 1/R4)^-1 does not equal the same thing. Please help? Thanks!
