The drift velocity is
Explanation:
From the question we are told that
The nominal diameter of the wire is
The current carried by the wire is
The power rating of the lamp is
The density of electron is
The current density is mathematically represented as
Where A is the area which is mathematically evaluated as
Substituting values
So
The drift velocity is mathematically represented as
Where e is the charge on one electron which has a value
So
