Hello,
Can someone tell me if I have the correct answer?
Thank You
my answer: B
A circuit contains two devices that are connected in parallel. If the resistance of one of these devices is 12 ohms and the resistance of the other device is 4 ohms, the total resistance of the two devices is?
A.0.333 ohms
B.3 ohms

DrBob222,
I don't think the question is exactly clear. The TOTAL resistance is obviously 12 + 4= 16 ohms; however, the resistance in the circuit is 3.0 ohms and your answer is correct. I think we can assume the person who wrote the question meant the total resistance in the circuit (in which they are parallel).
