1. In most household electrical systems, the materials used for conductors is either copper or aluminum. Metals are generally very good conductors, meaning they let current flow easily.
2. Insulators of heat and/or electricity are fur, silk, wool, rubber, percelain, glass, plastic, wood, paper, wax, ebonite. An insulator is anything that does not conduct electricity (electrical insulator ) or heat. Insulators are used to protect us from the dangerous effects of electricity flowing to conductors.
