Which term describes a device that absorbs electrical energy and converts it to light or heat?

• A. Conductor
• B. Insulator
• C. Source
• D. Load

Answer: (D)

In an electrical circuit, a load is the part that uses power from the source. It absorbs electrical energy and converts it into other forms, such as light or heat. A light bulb or a heater is a classic example, since electricity is transformed into visible light (and some heat) or into warmth. By contrast, a conductor mainly provides a path for current with low resistance, an insulator resists current to prevent flow, and a source supplies the energy. So the term for a device that absorbs electrical energy and turns it into light or heat is a load.
