AIIMS 2018 Physics Shunt Resistance MCQ Question

To find the shunt resistance $S$, we substitute the given values into the formula $S = \frac{I_g G}{I - I_g}$. Using $I_g = 0.5 \, \mu A = 0.5 \times 10^{-6} \, A$, $I = 5 \, A$, and $G = 50 \, \Omega^{-1}$, we calculate $S = \frac{(0.5 \times 10^{-6}) \times 50}{5 - 0.5 \times 10^{-6}} \approx 5 \times 10^{-6} \, \Omega$. The other options are not applicable since they do not provide valid answers or calculations related to the question.
