    A current of \[2\centerdot 5\,A\] flows through a coil of inductance 5 H. The magnetic flux linked with the coil is

    A) \[0\centerdot 5\,Wb\]

    B) \[12\centerdot 5\,Wb\]

    C) zero

    D) 2 Wb

    Correct Answer: B

    Solution :

    Here, \[I=2\,.\,5\,A,\,L=5\,H\] Magnetic flux linked with the coil is \[{{\phi }_{B}}=LI=\left( 5H \right)\left( 2\,.\,5\,A \right)\] \[=12\,.\,5\,Wb\].
