The electron drift speed is small and the charge of the electron is also small but still, we obtain large current in a conductor. This is due to

Options

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.

Answer

D

Explanation

It is because number of electrons per unit volume of a conductor is very large `(~~10^(28)m^(-3))`.
