1. The problem statement, all variables and given/known data Attached diagram. The resistors don't have any concrete resistances. Need to express the total resistance of the part of the circuit shown in the picture. 2. Relevant equations Series - R= ƩRn Parallel - R = (ƩRn-1)-1 3. The attempt at a solution R1 and R2 make a series - so the resistance of it would be R1+R2 and same with R4+R5. And using that approach I would have 3 parallel connections. R1+R2 R3 R4+R5 And compute the total resistance with the parallel formula...but, something just doesn't feel right.
