1. The problem statement, all variables and given/known data 2. Relevant equations Req =R1 + R2 Req = (R1*R2)/(R1 +R2) 3. The attempt at a solution No idea how to do that . Was thinking maybe making the 3 and 2 ohms resistors equivalent (assuming parallel). I have no idea what to do with the top wire . How do I simplify this circuit?
