Why is copper wire a better conductor of electricity than carbon fiber?

A. The electrons in copper (Cu) are loosely bound to the nucleus.

B. Copper (Cu) is a metal, and only metals can conduct electricity.

C. Carbon (C) does not have any valence electrons.

D. Copper (Cu) has no loose electrons.

A. The electrons in copper (Cu) are loosely bound to the nucleus.

Copper is a metal with a high number of free electrons that are able to move easily through the material, making it an excellent conductor of electricity. In contrast, carbon fiber is a non-metal material with fewer free electrons available for conducting electricity.
