A wire of resistance \(9 \Omega\) is bent to form an equilateral triangle. Then the equivalent resistance across any two vertices will be _____ ohm.
- A 4
- B 6
- C 8
- D 2
Answer & Solution
Correct Answer
(D) 2
Step-by-step Solution
Detailed explanation
\(9 \Omega\) is the resistance of whole wire \(\therefore\) resistance of each wire \(=3 \Omega\). \(\therefore\) Equivalent resistance \(=2 \Omega\)
