There are three conductors with a resistance of 2 ohms each. How should you connect them together so that the total resistance is 3 ohms?

Series connection of conductors:
R = R1 + R2 + R3 = 2 + 2 + 2 = 6 ohms.
Mixed connection of conductors:
R = R1,2 / 2 + R3 = 2/2 + 2 = 1 + 2 = 3 ohms.
Parallel connection of conductors:
R = R1 / 3 = 2/3 = 0.67 Ohm. This is true since R1 = R2 = R3.
Answer: In order to obtain a resistance of 3 ohms, two conductors must be connected in parallel and the third conductor must be connected to them in series.
