Vedclass · Answer

(A) In insulators,the energy band gap between the valence band and the conduction band is very large (typically $> 3 \ eV$).Because of this large energy gap,electrons cannot gain enough thermal energy to jump from the valence band to the conduction band.Consequently,the conduction band remains empty at all temperatures,preventing the flow of electric current.

In the case of insulators,the band gap and the conduction band are respectively:
