[Solved] The band gap between the valence band and conduction band is the measure of ______

The band gap between the valence band and conduction band is the measure of ______

a) The conductivity of the material
b) The resistivity of the material
c) Charge density
d) Ease of ionization

Answer: a
Explanation: The more the band gap between the valence band and conduction band, the worse is the conductivity of the material. For conductors, there are overlapping bands. So, conductors can carry electricity. But there is a huge energy gap in the case of insulators. So, they don’t carry electricity at all.
