When one coulomb charge passes through any cross section of the wire per second,the current passing is one ampere.
Charge of electron ,e=1.6X10^-19C.
Suppose, there are n electrons in 1C charge, then,
ne=1C
n=1/(1.6X10^-19)=6.25X10^18. This number of electrons passes through cross section of a wire carrying 1A current.
