Q. 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

KCETKCET 2006Current Electricity

Solution:

In a conductor, the electron number density i.e., number of electrons per unit volume of a conductor is very large $\left(=10^{28} m ^{-3}\right)$, so large current in a conductor is obtained irrespective of their small drift speed.
