Which term refers to a material that conducts electricity well?

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

Answer: (B)

Conductor describes a material that conducts electricity well. These materials have many free charge carriers, especially electrons in metals, that can move readily when an electric field is applied. That easy movement of charges leads to a larger current for a given voltage, i.e., low resistance and high conductivity. The word Ohm refers to the unit of resistance (and the scientist who formulated Ohm's law), not to a type of material. An electric field is the region around charges that exerts force on them, not a property of a material. Magnetism deals with magnetic forces and fields, not how easily a material conducts electricity. So the term that best fits a material that conducts electricity well is conductor.
