Define "conductor" in electrical terminology.

In electrical terminology, a conductor is defined as a material that permits the flow of electric current. This is primarily due to the availability of free electrons within the material, which can move easily when a voltage is applied, allowing electrical energy to pass through. Common examples of good conductors include metals like copper and aluminum, which are widely used in electrical wiring and components because they facilitate efficient transmission of electricity.

Understanding the role of a conductor is crucial for anyone working in the field of electrical engineering or wiring, as it forms the basis for designing circuits and electrical systems. A conductor's ability to carry current is essential for powering devices and ensuring proper functionality in various applications.
