How does the mobi

Answer :

If the drift velocity of the electrons is . Then, the mobility is



where is the electric field strength.


Also, if the electron density is , area of cross section is A, then



Also,



Combining all, we get



Now,



where is the length of conductor.


Thus,



Hence, mobility is independent of the voltage applied. Thus it remains same.
