If the electron drift speed is so small, and the electron’s charge is small, how can we still obtain large amounts of current in a conductor?

Current in the conductorI=Anevd​
wherenis the number density of free electrons,vd​is the drift velocity of electrons,eis its charge andAis the cross-section area of conductor.
Conductors have very large number density of free electrons, nearly1028cm−3, which conduct electric current in the conductor. Thus inspite of having small drift velocity and electronic charge, we obtain large current in the conductor.
