HOLA :)
DRIFT VELOCITY :
the electrons in the conductor move with a constant average speed, known as drift speed or drift velocity .... (Vd)
* drift speed/ velocity = I / nqA
where I = current
n = number of charges ( electron density )
q = magnitude of the charge
A = area of cross section of the conductor
