    Magnetic flux in a circuit containing a coil of resistance \[2\Omega \]changes from 2.0 Wb to 10 Wb in 0.2 sec. The charge passed through the coil in this time is    [DPMT 2003]

    A)            0.8 C                                        

    B)            1.0 C

    C)            5.0 C                                        

    D)            4.0 C

    Correct Answer: D

    Solution :

               \[q=\frac{N}{R}(\Delta \varphi )=\frac{1}{2}\times (10-2)=4C\]
