The charge on an electron is negative and it is -1.6 * 10^-19 coloumb, therefore, 1C charge is carried by 1/(-1.6 * 10^-19) = 6.25 * 10^18 electrons.
Hence, if 1A current flows through a conductor, it implies that 6.25 * 10^18 electrons pass per second across the cross-section of the conductor.
Kindly, ask me if you have any doubts. If you are satisfied with my answer, don't forget to mark my answer as the brainliest.

Given that
Charge (Q) = 1 C
Electron (e) = 1.6× 10^-19
Number of electron (n) = ?
Q= ne
1 C = n × 1.6×10^-19 C
n = 1/(1.6×10^-19)
n = 6.25 × 10^18 electron
