1. The problem statement, all variables and given/known data Ignore the internal resistance of the battery and assume it is merely a battery. Calculate the equivalent resistance of the circuit. 2. Relevant equations 1/Req = 1/R + 1/R ... (parallel) Req = R + R .... (series) 3. The attempt at a solution I know this is fairly simple but I dont understand how you would calculate the equivalent resistance for the three resistors (3.2 ohms, 7.1 ohms, 5.8 ohms). I assumed they were in series and simply added them, and then added 1.0 ohms and 4.5 ohms to get the total resistance. I think this is wrong, can someone explain how you would go about calculating the Req?
