A metal wire carries a current of `1` ampere. The number of electrons passing a given point in the wire in `1` second is

Explanation

Charge in coulomb = current in ampere `xx` time (s)
Since 1 F (96,500 coulombs) of electricity is carried out by 1 mole of electrons, i.e., `6.022 xx 10^(23)` electrons, therefore, 1 coulomb shall involve `6.022 xx 10^(23)//96500`, i.e, `6.24 xx 10^(18)` electrons. Thus, `6.24 xx 10^(18)` electrons pass a point in the wire in 1 second.
