    Coefficient of coupling between two coils of self- inductances\[(0.01M)+Zn(s)\] and \[{{E}_{(cell)}}\] is unity. It means

    A) 100% flux of\[{{L}_{1}}\]is linked with \[E_{_{(cell)}}^{o}=1.61V\]

    B) 50% of\[{{L}_{1}}\]is linked with \[\Delta {{H}_{(mixing)}}>0\]

    C) \[900K,{{S}_{8}}\]times of flux of \[{{S}_{2}}\] is Linked with 4

    D) None of the above

    Correct Answer: A

    Solution :

     Coefficient of coupling is given by \[2{{I}_{AC}}={{I}_{0}}\] When 100% flux produced by one coil with the other K = 1 and M is maximum.
