Question

The atoms of copper contain electrons and the atoms of rubber also contain electrons.them why does copper conduct electricity but rubber does not conduct electricity

Answer 1

Any substance can conduct electricity only if it has free electrons.

It is true that copper and rubber, both have electrons but copper has free electrons, which are responsible for flow of current and hence, conduct electricity.

Rubber, on the other hand, does not have free electrons and cannot conduct electricity and are called insulators.

Answer 2

Explanation:

any substance can conduct electricity only if it has free electrons...

copper conducts electricity because it has free electrons and these free electrons allow the flow of current. That's why copper conducts electricity

but on the other hand rubber does not conducts electricity because it do not have free electrons ..so it does not conducts electricity
