In a meter bridge, the gaps are enclosed by resistances of \(2 \Omega\) and \(3 \Omega\). The value of shunt to be added to \(3 \Omega\) resistor to shift the balancing point by \(22.5 \mathrm{~cm}\) is
- A \(1\ \Omega\)
- B \(2\ \Omega\)
- C \(2.5\ \Omega\)
- D \(5\ \Omega\)
Answer & Solution
Correct Answer
(B) \(2\ \Omega\)
Step-by-step Solution
Detailed explanation
(Initial part) \(\frac{x}{100}-x=\frac{2}{3} \Rightarrow x=40 \mathrm{~cm}\) If there is shifting by \(22.5 \mathrm{~cm}\). Then, to obtain the balance point in meter bridge…
