    Hi

    We know that,

    The current is given by
    i =Q/t
    Then
    Q =i t

    Now,Q =2×1=2C

    Also,

    charge Q is due to electrons, then
    Q =N×e


    Where,N is the number of electrons passing and e is  1.6×10−19 i.e charge on electron

    Then,
    N =Q/e= 2/ 1.6×10^−19

    =1.25×10^19electrons


    Thus , flow of 2 ampere of currents corresponds to flow of 1.25×10^19electrons electrons

    Thank you

    Rashi You have said in question that current is 2 ampere. so 2 coulomb charge flows per second. so , Q=2 coulomb
