A circuit contains twodevices that are connected in parallel. If the resistance of one of these devices is 12 ohms and the resistance of the other devices is 4 ohms, the total resistance of the two devices is?


1/R = 1/R1 + 1/R2
You have R1 and R2. Solve for R.
It will be less than the least R in the parallel circuits.
