What does the term "conductivity" refer to in electrical terms?

The term "conductivity" refers specifically to the ability of a material to conduct electricity. This property is crucial in electrical applications, as it determines how well an electric current can flow through a material. Conductivity is typically measured in terms of how easily electrons can move within the material when an electrical potential is applied. Materials with high conductivity, such as metals, allow electricity to flow easily, while those with low conductivity, like insulators, do not facilitate the flow of electricity effectively.

Understanding conductivity is vital in the context of designing electrical systems, selecting appropriate materials for wiring, and ensuring efficient energy transfer. This is why the correct answer is focused on the capability of a material to conduct electricity.
