Why do you think air is such a poor conductor com-pared to a metal (at normal field strengths)?
A) Air is much less dense than a metal.
B) Electrons can travel much farther in a metal before col-liding with an atom than they can in air.
C) Air molecules are much bigger than metal atoms.
D) Electrons move much more slowly in air.
E) Air normally has very few free charge carriers.

Question
