Question

what are electric insulators?​

Answer 1

Answer:

$\huge \color{purple}\underbrace{Answer}$

• "An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field.

• INSULATORS, The conduction band of those material remains empty. The forbidden energy gap between the conduction band and the valence band is widest. The difference is more than 10ev. Crossing the forbidden energy gap from valence band to conduction band large amount of energy is needed.

Answer 2

An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons.

electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
