Which of the following is NOT a characteristic of conductors?

The choice indicating that conductors have high resistance is not a characteristic of conductors. Conductors are materials that allow electricity to flow freely due to their low resistance. Low resistance is a defining feature of conductors, as it facilitates the movement of electric charges through the material with minimal energy loss. This property is crucial for the efficiency of electrical systems.

In contrast, options that explain the characteristics of conductors include their ability to allow electricity to flow (which is fundamental to their definition), their tendency to heat up during electrical flow due to the resistance present (albeit low), and their capacity to easily transfer heat, which is often the basis for their use in various thermal and electrical applications. These attributes underscore the efficient conductive nature of such materials while maintaining low resistance.
