Answer:
The resistivity of the wire is not directly proportional to the current density.
Option (e) is correct
Explanation:
Given:
In the Drude model of electrical conduction, the current density is NOT directly proportional to
According to the Drude model, current density is given by.
⇒ [tex]J = (\frac{nq^{2} t}{m} )E[/tex]
Where [tex]n =[/tex] the number of charge carriers per unit volume, [tex]q =[/tex] electron charge, [tex]t =[/tex] the average time interval between successive collisions, [tex]E =[/tex] electric field present in the wire.
So from the above equation we conclude that resistivity of the wire is not directly proportional to the current density.
