What are Conductors and Insulators?

Conductor:

Conductors are those materials which allow the flow of electrons from one particle to another without any restriction. A conducting material allows the transfer of charge throughout the surface of the body. You can check a conductor by giving charge at specific location to conductor. In conductors, charge spreads throughout the body. This distribution of charge occurs because of the following electron. Conductor can even transfer its charge to the other object

Insulator:

In contrast to conductors, insulators are the materials that fully block the flow of electrons which as a result does not allow the flow of charge. Insulators can be detected as the charge will remain at a specific location where the charge is supplied. It does not distribute the charge throughout the body.
