Conducted is not opposes the free elecrons and semiconductor is both acts as opposes the free elecrons are not but insulator is purely opposes the free elecrons.

All of the above should be the answer as there is no conductor/semiconductor that doesn't oppose electron in the practical scenario.

Whai is free electron?

For insulator the depletion region width is high between the valance band and conduction band. So there is no flow of free electrons.

In insulators there is a large forbidden gap in between conduction band n vacancy band. So practically it s impossible for electron to jump from valence band to conduction band. So such materials cannot conduct so these are called insulators e.x diamond, glass wood.

Why insulators does not allows the current?

INSULATOR.

Because, insulator is bad conductor of heat. That means it opposes the flow of electron in it.

What type of material used in conductor, insulator and semi conductor?

Thangapandiyan said:   1 decade ago
Electron tightly packed so no move the electrons so doesn't current flow.

Because in insulator the atoms are tightly bound with nucleus so their is no possibility of movement of charge carriers so their is no flow of current.
