Insulators also contain electrons, but they are not conductors, Why?

Question:

Insulators also contain electrons, but they are not conductors, Why?

Electric Current:

An electric current is a flow of electric charges within a given material under the action of an applied voltage (electric field).

The capability of a material to conduct an electric current is described by the electric conductivity.

Answer and Explanation:

An electric insulator is a material characterized by a very low electric conductivity (high electric resistivity).

Unlike electric conductors, insulators contain electrons by a only few of them are free to move and then very little current flows

under the application of an external electric field.
