    A tangent galvanometer has a reduction factor of 1 A and it is placed with the plane of its coil perpendicular to the magnetic meridian. The  deflection produced when a current of 1 A is passed through it is:

    A)  \[{{60}^{o}}\]                                   

    B)  \[{{45}^{o}}\]

    C)  \[{{30}^{o}}\]                                   

    D)  none of these

    Correct Answer: B

    Solution :

    Deflection in tangent galvanometer                 \[\tan \theta =\frac{1}{K}\] where K= reduction factor                 \[\tan \theta =\frac{1}{1}\]                                 \[=1=\tan \,{{45}^{o}}\] \[\therefore \]                  \[\theta ={{45}^{o}}\]
