Which term describes any material that can carry an electrical current, and may also conduct heat?

• A. Insulator
• B. Conductor
• C. Semiconductor
• D. Dielectric

Answer: (B)

A conductor is a material that allows electric current to pass through it. These materials not only carry charge but often also conduct heat, because the same free electrons that move to carry electricity also transfer energy as they collide and vibrate within the material. That’s why metals like copper or aluminum are good both at conducting electricity and heat. Insulators resist the flow of electricity and typically don’t conduct heat well. Dielectrics are insulating materials that can store electric charge but do not conduct current under normal conditions. Semiconductors can conduct electricity but only under certain conditions or with doping, so they’re not universal conductors. So, the term that describes any material that can carry an electrical current (and may also conduct heat) is conductor.
