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

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).
if the total resistance of two circuits in parallel is 4 ohms and one circuit has twice the resistance of the other, find the resistance of each circuit
