Question
A cuircuit contains two devices that are connected inparallel. If the resistance of one of these devices is12 ohms andthe resistance of the other device is 4 ohms, the total resistanceof the two devices is (a) 0.0625ohms (c) 3 ohms (b) 0.333ohms (d) 16 ohms A cuircuit contains two devices that are connected inparallel. If the resistance of one of these devices is12 ohms andthe resistance of the other device is 4 ohms, the total resistanceof the two devices is (a) 0.0625ohms (c) 3 ohms (b) 0.333ohms (d) 16 ohmsExplanation / Answer
1/R = 1/12 + 1/4 R = 3 answer: (c) 3 ohms
