a solid substance that conducts electricity or heat better than insulators, but not as well as most metals
semiconductor
a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures
superconductivitate
to apply an electric charge to a conductor
electrifica, încărca electric
a conductor through which electricity travels to or from an object, such as batteries
