If only \(5 \%\) of the total current is to be passed through galvanometer of resistance G, then the resistance of the shunt will be
- A \(\frac{\mathrm{G}}{15}\)
- B \(\frac{\mathrm{G}}{17}\)
- C \(\frac{\mathrm{G}}{19}\)
- D \(\frac{\mathrm{G}}{21}\)
Answer & Solution
Correct Answer
(C) \(\frac{\mathrm{G}}{19}\)
Step-by-step Solution
Detailed explanation
\(I_g = 0.05 I\) \(I_s = I - I_g = I - 0.05 I = 0.95 I\)
