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
