Which material is an example of a good conductor?

• A. Wood
• B. Rubber
• C. Copper
• D. Glass

Answer: (C)

Copper is known as an excellent conductor of electricity due to its high electrical conductivity. This property allows electric current to flow through copper easily, making it an ideal choice for electrical wiring and components. The atomic structure of copper allows electrons to move freely, which is what facilitates the efficient transmission of electrical energy. In contrast, materials such as wood, rubber, and glass are considered poor conductors, or insulators. These materials do not allow electrons to flow freely, thus inhibiting the movement of electric charge and making them unsuitable for conducting electricity.
