Thank you good explaination.

The Difference between conductors and insulators is that conductors conduct electricity and insulators does not.On the basis of energy band theory conductors have partially filled valence band and insulators has fully filled valence band.

In  case of conductor, conduction band and valence band are overlapping, n therefore electrons are very free to move. But in Semiconductors there is a bit distance between the their valence band and conduction band. When there are heated electron jump to the conduction band from the valence band but in case of Insulators there is … Read more
