    If reduction factor of a tangent galvanometer is 900 mA, then the current through it to produce a deflection of\[45{}^\circ \]is:

    A)  600 mA     

    B)  700 mA

    C)  750 mA     

    D)  900 mA

    Correct Answer: D

    Solution :

     The current flowing in coil  of galvanometer is \[i=k\,\tan \theta \] \[=900\times {{10}^{-3}}\times tan45{}^\circ \] \[=900\times {{10}^{-3}}\] \[=900mA\]
