1. The problem statement, all variables and given/known data uploaded is the circuit with resistors technically in series. R1 had a measured value of 160 ohms (from A to B) 0.0617 Amps R2 had a measured value of 387 ohms (from B to C) 0.025 amps from A to C the resistance measured is 243.9 ohms 0.041 amps this means that there is a parallel resistance some where in between but I do not know how to solve to find which is which. 2. Relevant equations for series R1+R2...=Rtotal for parallel (R1*R2)/R1+R2 I=V/R 3. The attempt at a solution I tried 243.9=162+(R3R4)/R3+R4 assuming one of the resistors are not parallel.
