What does electrical conductivity indicate about a material?

Electrical conductivity is a key property that indicates how well a material can conduct an electric current. This characteristic is crucial in various applications, particularly in electronics, where materials with high conductivity, such as metals, are used to create effective conductive pathways for electric charges.

The ability of a material to allow electric current to flow is determined by its atomic structure and the presence of free electrons. High conductivity means the material allows electric charges to move freely, making it suitable for use in wires, circuits, and other electrical components.

In contrast, resistance to force, weight, or thermal properties pertains to different material characteristics that do not directly relate to electrical conductivity. Resistance to force pertains to mechanical properties, weight refers to mass rather than the ability to conduct electricity, and thermal properties deal with heat transfer rather than electrical behavior. Therefore, B captures the fundamental definition and significance of electrical conductivity accurately.
