What term describes a material that has little resistance and allows easy movement of electrons?

The term that describes a material with little resistance that allows for the easy movement of electrons is a conductor. Conductors, such as metals like copper and aluminum, possess a high number of free electrons that can move easily through the material. This property enables them to facilitate the flow of electric current with minimal energy loss, making them essential in electrical wiring and components.

In contrast, insulators are materials that impede the flow of electrons, thus preventing current from passing through easily. Semiconductors have conductivity levels that lie between those of conductors and insulators; they can conduct electricity under certain conditions but not as readily as conductors. Resistors are components specifically designed to limit or control the flow of electrical current in a circuit rather than enabling easy movement. Therefore, the characteristics of a conductor align perfectly with the definition presented in the question.
