Insulators does not allow flow of electricity. It has no free electrons. I think a described c answer is wrong.

Yes insulator have no free electron. Then how option C is right? It must be D.

Anshuma said:   1 decade ago
But practically it is not possible @basha, if it is possible describe how?

Aman sajwan said:   7 years ago
The answer should be d D because an insulator hasn't any free electron.

The insulator has no charge carrier. So the answer should be D.

George said:   8 years ago
Option C is correct because there is no perfect insulator.

Santhoshnaini said:   1 decade ago
Actually its no, because its have no electrons.

Kallappa said:   10 years ago
Insulator has some free Electrons.
