    In a circuit with a coil of resistance 2 ohms, the magnetic flux changes from 2.0 Wb to 10.0 Wb in 0.2 second. The charge that flows in the coil during this time is [MP PMT 1997]

    A)            5.0 coulomb                         

    B)            4.0 coulomb

    C)            1.0 coulomb                         

    D)            0.8 coulomb

    Correct Answer: B

    Solution :

               \[\Delta Q=\frac{\Delta \varphi }{R}=\frac{\left( 10-2 \right)}{2}=4C\]
