What term describes a material that conducts electricity?

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

Answer: (D)

Classifying materials by how well they conduct electricity helps predict how they'll behave in circuits. A material that conducts electricity readily is called a conductor. Metals like copper and aluminum are classic examples because their electrons flow easily when a voltage is applied. An insulator, in contrast, resists the flow of current and has very low conductivity, which is why it’s used to protect and separate conductive parts. A semiconductor sits between these two in terms of conductivity, and its ability to conduct can change with conditions like temperature, light, or doping. A battery isn’t a material type describing conduction; it’s a device that stores chemical energy and provides electrical energy when used in a circuit. So the best term for a material that conducts electricity is conductor.
