Three 6 ohm resistors are connected to form a triangle. What is the resistance between any two corners ___________?
Correct answer: C. 4 Q
- A. 3/2 Q
- B. 6 Q
- C. 4 Q
- D. 8/3 Q
Explanation
Between two corners of the triangle, one 6 Ω resistor is in parallel with the other two in series, which equal 12 Ω. Their equivalent is 6 || 12 = (6×12)/(6+12) = 4 Ω.
