1. The problem statement, all variables and given/known data Find the equivalent resistance at terminals a-b of the circuit. 2. Relevant equations Resistors in parallel : 1/Req = 1/R1 + 1/R2...+...1/Rn Resistors in series: Req = R1 + R2...+...Rn 3. The attempt at a solution The resistors are in ohms and the answer is 32.5 ohms. The diagram is in the link and so is my work.
