A material that conducts electricity well is called what?

• A. Conductor
• B. Electric field
• C. Magnetism
• D. Polarization

Answer: (A)

Materials that conduct electricity well are called conductors. This is because they have many free electrons that can move in response to an electric field, so charges flow easily and create an electric current with relatively little resistance. The electric field is the region that exerts the force on charges, not a material itself. Magnetism concerns magnetic effects and fields, not how readily a material conducts. Polarization refers to the alignment of charges inside a material when an electric field is applied, a behavior more typical of insulators than good conductors. So the term that fits describes a conductor.
