A conductor is defined as a material that allows the flow of electricity. This is due to the presence of free electrons in the material, which can move easily and facilitate the transfer of electrical energy. Common conductors, such as copper and aluminum, have a high electrical conductivity, meaning they allow electrical current to pass through them with minimal resistance. This property makes conductors essential for wiring and electrical components in circuits, as they provide a pathway for electricity to travel from one point to another.

In contrast to this concept, other options refer to either materials with opposite properties, such as insulators which resist electrical flow, devices that manage electrical systems rather than conduct current, or circuit types which are structured arrangements involving various electrical components. These distinctions clarify why the correct answer accurately describes the fundamental role of conductors in electrical applications.
