Good conductors are materials that allow electricity to flow through them easily. METAL, MAESTRO, and WIRE are all examples of good conductors. METAL is a solid material made up of one or more elements that can be melted and shaped into different forms. MAESTRO is a term used to refer to a conductor of an orchestra or other musical ensemble. WIRE is a thin, flexible strand of METAL that is used to carry electricity. All three of these materials are good conductors of electricity and are used in many electrical applications.
