WebConductors are substances that an electric charge can pass through without difficulty. An electric charge cannot pass through an insulator easily. Different types of atoms make a substance a conductor or an insulator. All substances are made of atoms. Each atom is made of particles called electrons orbiting around a central nucleus. WebMaterials 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. Most items made of plastic and rubber are insulators.
