10 Examples of Electrical Conductors and Insulators

10 Examples of Electrical Conductors and Insulators10 Electrical Insulators. Most metals are better conductors when cool and poorer conductors when hot. Some good conductors become superconductors at extremely low temperatures. Although electrons flow through a conductive material, they don't damage the atoms or cause wear, like you would get from friction of water in a canyon, for example.
