Conductors are substances that enable free electrons to flow through them quickly. This process transfers energy in the form of electricity as electrons move freely from atom to atom. Conductors also permit electrons to run rapidly from particle to particle in one or more directions. It hits a free electron and knocks it off, and it eventually knocks off other free electrons.
This process sets off a chain reaction creating an electrical charge through the material. Most metals such as gold, silver, iron, aluminum, and copper are efficient conductors. On the other hand, insulators are substances that have precisely the opposite effect on the flow of electrons.
These substances hinder the flow of direction, thus preventing the flow of electrical currents. Some examples of efficient insulators include: Glass has the highest resistivity, Plastic makes countless products. Rubber is also an excellent insulator. In makes tyers, fire-resistant clothes and slippers
