Conductor and Insulator

Conductor

Conductor is substances which allow electricity to flow through them.

Example of conductors are metals like

·         Iron,

·         Copper,

·         Steel

·         Constantan

In conductors’ electrons are free to move which are conduct charge from one to another 

 

Insulator

Insulator is a material that does not allow electricity to flow through them.

Examples of insulators are;

·         Plastic,

·         Wood,

·         Rubber,

·         Mica,

·         Ebonite and

·         Glass.

In insulators there are no free electrons for conduction.
