Ampere is the unit of measutement of electric current.It’s the rate of flow of charge.
Mathematically,
1 columb/second = 1 Ampere.
1.6×10—^19 is the charge on one electron.Current is not rate of flow of electrons,but that of charge and charge could be there on Ions too.
It would be number of electrons passing through a particular crosssection holding a 1 columb of charge in one second.
In other words,
the number of electrons required to make 1 columb of charge is 1/1.6 * 10^-19
=6.67×10^18 electrons.
So, 6.67×10^18 electrons. would pass through a particular crosssesction of an electric conductor per second,then it would result in 1 ampere of current.
Finally, once again I would wind up saying, current is rate flow of charges and not that of electron.
