The charge on an electron is negative and it is -1.6⨯10-19 coulomb therefore, 1 C charge is carried by 1/ (-1.6⨯10-19) = 6.25 ⨯ 1018 electrons. Hence if 1 A current flows through a conductor, it implies that
6.25 ⨯ 1018 electrons pass per a second across the cross section of the conductor.
6.25 ⨯ 1018 electrons pass per a second across the cross section of the conductor.

Q = 1 c
Q= n *e
=> 1 = N * 1.6 * 10^(-19)
=> 1 = 1.6 * N / 10^19
=> 10^19 = 1.6 N
=> N = 10^19 / 1.6
=> N = 0.625 * 10^19
=> N = 6.26 * 10^18
No. Of electrons = 6.25 * 10^18
