Electron drift velocity

Suppose that,that in a conductor  the number of electrons available per m3 of the conductor material is n. Let there axist drift velocity is v.

In that in dt distance traveled would be v*dt. If A area of cross section of a conductor material , than is a volume is v dt .then the number of electrons is that of volume is v dt . obviously all these electrons will be cross contained of cross section in time is dt.if e is charge in each electrons, then the total charge of cross section in time dt is dq =n Aev dt.
