A) 10\[\Omega \]
B) 1\[\Omega \]
C) 0.1\[\Omega \]
D) 12.48\[\Omega \]
Correct Answer: C
Solution :
Resistance of galvanometer coil, \[R=10\,\,\Omega \] Current \[=1\,\,\,mA\] Range of current: \[0-100\,\,mA\] So, the shunt resistance is \[S=\frac{{{I}_{g}}R}{I-{{I}_{g}}}\] \[=\frac{1\times {{10}^{-3}}\times 10}{100\times {{10}^{-3}}-1\times {{10}^{-3}}}\] \[=\frac{10}{99}=0.10\,\Omega \]
