A) the conducting property of the conductor
B) the resistance of the conductor is small
C) the electron number density of the conductor is small
D) the electron number density of the conductor is enormous
Correct Answer: D
Solution :
In a conductor, the electron number density ie, number of electrons per unit volume of a conductor is very large \[(\approx {{10}^{28}}{{m}^{-3}}),\] so large current in a conductor is obtained irrespective of their small drift speed.
