Question

Quizplus · Accepted Answer

Insulators are materials that have high resistance and do not allow electrons to flow through them easily. Examples include rubber, glass, and air. Alternators and thermocouples are devices that convert energy from one form to another and are not materials. Conductors, on the other hand, are materials that allow electrons to flow through them easily, such as metals like copper and aluminum.
