A straight wire of resistance \(18 \Omega\) is bent in the form of an equilateral triangular loop. The effective resistance between any two vertices of the traingle is
- A \(6 \Omega\)
- B \(3 \Omega\)
- C \(1 \Omega\)
- D \(4 \Omega\)
Answer & Solution
Correct Answer
(D) \(4 \Omega\)
Step-by-step Solution
Detailed explanation
Resistance of each side \(R_{side} = \frac{18 \Omega}{3} = 6 \Omega\). Between any two vertices, one path has \(R_1 = 6 \Omega\). The other path has \(R_2 = 6 \Omega + 6 \Omega = 12 \Omega\). Effective resistance…
