  • question_answer
    A coil having an inductance of 0.5 H carries a current which is uniformly varying from zero to 10 ampere in 2 second. The e.m.f. (in volts) generated in the coil is    [Kerala PET 2005]

    A)            10  

    B)            5    

    C)            2.5

    D)            1.25

    Correct Answer: C

    Solution :

                       \[\left| e \right|=L\left| \frac{di}{dt} \right|=0.5\times \frac{10}{2}=2.5V\]
