Question: 1 / 400

What is a conductor designed to transmit?

a group of stars that form a pattern in the sky

the preservation and careful management of the environment

electricity, heat, etc.

The correct answer is that a conductor is designed to transmit electricity, heat, and similar forms of energy. Conductors are materials that allow the flow of electric current or thermal energy due to their atomic structure, which permits the movement of charge carriers (like electrons). For example, metals such as copper and aluminum are commonly used as electrical conductors because they have many free electrons that move easily when voltage is applied.

In contrast, the other options do not pertain to the function of a conductor. The first option mentions celestial patterns, which relates to astronomy rather than the transmission of energy. The second option focuses on environmental management, which is more about conservation practices. The last option describes a type of geological material, rather than a physical medium that transmits energy.
