In the given circuit, the equivalent resistance between \(\mathrm{A}\) and \(B\) is
- A \(3 \Omega\)
- B \(4 \Omega\)
- C \(5: 5 \Omega\)
- D \(5 \Omega\)
Answer & Solution
Correct Answer
(D) \(5 \Omega\)
Step-by-step Solution
Detailed explanation
\(R_1 = R_2 = R_3 = R_4 = R_5 = 5 \, \Omega\) (assumed for a common balanced Wheatstone bridge configuration where \(R_{eq}=R\)) Bridge balance condition: \(R_1/R_3 = R_2/R_4 \implies 5/5 = 5/5\). Thus, the bridge is balanced. \(R_5\) (the central resistor) is ineffective.…
