1. The problem statement, all variables and given/known data A network consists of a combination of parallel and series connections. What is the equivalent resistance of the network? (Hint: Use the series and parallel resistance formulas). The network looks like this: 2. Relevant equations When a circuit is in series, R = R1 + R2 + R3... When a circuit is in parallel, R = 1/R1 + 1/R2 + 1/R3... 3. The attempt at a solution First, c and b are in series, so I just add them up. 5 + 3 = 8. Now, a, d, and this new resistor of value 8 are in series. So add them up again. 8 + 4 + 1 = 13. Did I do that correctly?
