WebAboutTranscript. A 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 ... WebSep 23, 2024 · Other materials, such as rubber, wood, glass, and dry cotton, are not good conductors because the electrons within these materials cannot move about freely. Therefore, heat and energy are not ... WebIn metals, the outer electrons are loosely bound to their atoms, so not much energy is required to make electrons move through metal. Such metals as copper, silver, and aluminum are good conductors. Insulating materials include plastics, glass, ceramics, and wood. The conductivity of some materials is intermediate between conductors and … banding fs ditolak
