Which term describes a material that allows electrons to move freely and conduct electricity?

The term that describes a material which permits electrons to move freely, enabling it to conduct electricity, is electrical conductor. Materials such as metals (e.g., copper and aluminum) are good conductors because they have free-moving electrons that can carry an electric charge. In contrast, electrical insulators are materials that do not allow free movement of electrons, thus preventing the flow of electricity. Electrical resistors are components that restrict the flow of electric current and are used to control voltage and current in circuits, while electrical dielectrics are materials that are poor conductors but can store electrical energy in an electric field, primarily used in capacitors. Understanding these distinctions is essential in electrical studies, as it helps in identifying which materials are suitable for various applications in circuits.
