In a meter bridge experiment. a resistance of \(9 \Omega\) is connected in the left gap and an unknown resistance greater than \(9 \Omega\) is connected in the right gap. If the resistance in the gaps are interchanged, the balancing point shifts by 10 cm . The unknown resistance is
- A \(18 \Omega\)
- B \(22 \Omega\)
- C \(11 \Omega\)
- D \(36 \Omega\)
Answer & Solution
Correct Answer
(C) \(11 \Omega\)
Step-by-step Solution
Detailed explanation
In meter bridge experiment, \(\frac{9}{x}=\frac{1}{100-1}\) ...(i) Again, \(\frac{x}{9}=\frac{1+10}{100-(1+10)}=\frac{1+10}{90-1}\) ...(ii) Multiplying eq(i) and (ii), we get…
