    Calculate the current which will produce a deflection of 30° in a tangent galvanometer, if its reduction factor is 3 A.

    A)  1.732 A                               

    B)  0.732 A

    C)  3.732 A                               

    D)  2.732 A

    Correct Answer: A

    Solution :

                     From the relation \[I=k\text{ }\tan \theta \] \[=3\tan {{30}^{o}}=3\times \frac{1}{\sqrt{3}}=\sqrt{3}=1.732A\]
