    A galvanometer of resistance \[20\,\Omega \] is to be converted into an ammeter of range 1A. If a current of 1 mA produces full scale deflection, the shunt required for the purpose is:

    A)  \[0.01\,\Omega \]                         

    B)  \[0.05\,\Omega \]         

    C)  \[0.02\,\Omega \]         

    D)         \[0.04\Omega \]

    E)  \[0.03\Omega \]

    Correct Answer: C

    Solution :

    \[S=\frac{{{I}_{g}}G}{I-{{I}_{g}}}=\frac{{{10}^{-3}}\times 20}{1-1\times {{10}^{-3}}}=0.02\,\Omega \]
