Weegy: 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 3 ohms.
Solution:
I/R=I/r1+ 1/r2.
Explanation:
12 x 4 divide d by 12+4= 48/16=3
Total Resistance = 3 ohms. ]
