WebA conductor is a material that allows electrons to flow freely through it, making it useful for carrying electric current. An insulatoris a material that resists the flow of electrons, so it does not allow electric current to pass through it. Learn about how conductors and insulators work and how they are effected by changes in electrical current. WebFeb 22, 2024 · O Cork is a bad conductor of heat. O Copper is a bad conductor of heat.

WebThere are many materials that can be used to “close” a circuit, or allow current to flow. Materials that allow electric current to flow through easily are called conductors. Most metals including aluminum are good conductors of electricity as well as water. Materials that do not allow electric current to flow well are insulators.
