A uniform wire has resistance of \(24 \Omega\). It is bent in the form of a circle. The effective resistance between the two points on any diameter of the circle is _________.
- A \(12 \Omega\)
- B \(24 \Omega\)
- C \(6 \Omega\)
- D \(3 \Omega\)
Answer & Solution
Correct Answer
(C) \(6 \Omega\)
Step-by-step Solution
Detailed explanation
(C)
The resistance of each semi circular part will be \(12 \Omega\).

Both \(12 \Omega\) are in parallel
\(R_{e q}=\frac{12 \times 12}{12+12}=6 \Omega\)
The resistance of each semi circular part will be \(12 \Omega\).

Both \(12 \Omega\) are in parallel
\(R_{e q}=\frac{12 \times 12}{12+12}=6 \Omega\)
