In insulators________. (C.B is conduction band and V.B is valence band)

Question

Verified by Toppr

Answer 1

As shown in the image, insulators have a very large forbidden gap. Their conduction band is empty, thus they cannot conduct electricity under normal room temperature and pressure conditions. The valence band is full.

Answer 2

As shown in the image, insulators have a very large forbidden gap. Their conduction band is empty, thus they cannot conduct electricity under normal room temperature and pressure conditions. The valence band is full.

C.B. is partially filled with electrons

C.B. is empty and V.B. is filled with electrons

C.B. is filled with electrons and V.B. is empty

As shown in the image, insulators have a very large forbidden gap. Their conduction band is empty, thus they cannot conduct electricity under normal room temperature and pressure conditions. The valence band is full.
