    The resistance of 1 A ammeter is \[0.018\,\Omega \]. To convert it into 10 A ammeter, the shunt resistance required will be [MP PET 1982]

    A)                    \[0.18\,\Omega \]

    B)                                      \[0.0018\,\Omega \]

    C)                    \[0.002\,\Omega \]

    D)            \[0.12\,\Omega \]

    Correct Answer: C

    Solution :

                 \[S=\frac{{{i}_{g}}G}{(i-{{i}_{g}})}\]\[=\frac{1\times 0.018}{10-1}=\frac{0.018}{9}=0.002\Omega \]
