  • question_answer
    In a moving coil galvanometer, the deflection of the coil \[\theta \] is related to the electrical current i by the relation                          [MP PMT 1996, 2000, 03; RPMT 1997; CPMT 1975; MP PET 1999]

    A)            \[i\propto \tan \theta \] 

    B)            \[i\propto \theta \]

    C)            \[i\propto {{\theta }^{2}}\]   

    D)            \[i\propto \sqrt{\theta }\]

    Correct Answer: B

    Solution :

               \[i=\frac{C\theta }{NAB}\] Þ \[i\,\propto \theta \]
