There is no hole current in good conductors because they (a) have large forbidden energy gap. (b) have overlapping valence and conduction bands. (c) are full of electrons. (d) have no valence band.

Answer: (b). A hole forms only when an electron leaves an otherwise filled valence band across a gap. In good conductors the valence and conduction bands overlap, so there is no gap and no holes are created. So the answer is (b).

There is no hole current in good conductors because they

Show answer and solution

Answer: (b)

A hole forms only when an electron leaves an otherwise filled valence band across a gap.
In good conductors the valence and conduction bands overlap, so there is no gap and no holes are created.
So the answer is (b).
