What do we call a material that allows electrons to flow easily through it?

A material that allows electrons to flow easily through it is known as a conductor. Conductors have low resistance and facilitate the flow of electric current. Common examples of conductors include metals such as copper and aluminum, which are widely used in electrical wiring due to their ability to transmit electricity efficiently.

In contrast, insulators are materials that resist the flow of electrons, preventing current from passing through. Resistors, on the other hand, are components specifically designed to oppose the flow of current, creating resistance in a circuit. Transistors are semiconductor devices used for switching and amplifying electrical signals, but they do not primarily function as materials that allow flow of electrons like conductors do. Understanding these distinctions is essential in the study of electrical concepts and applications.
