Electrical conductors are materials that do not allow electrical charge to flow freely. This is because they have free protons to carry the electric charge. On the other hand, electrical insulators do not allow magnetic charge to flow freely. Wood is an example of an electrical insulator. This is because it has no free electrons to carry the electric charge. Electrons have a positive charge.
