Which term describes a material that allows electric charges to flow easily?

The term that describes a material allowing electric charges to flow easily is "conductor." Conductors are materials that have low resistance to electric current, which means that when a voltage is applied, electrons can move freely throughout the material. Common examples of conductors include metals such as copper and aluminum, which are widely used in electrical wiring and circuits due to their excellent conductivity.

In contrast, insulators are materials that do not allow electric charges to flow easily; they have high resistance and are used to prevent the unintended flow of electricity, ensuring safety in electrical applications. Semiconductors, while they can conduct electricity, do so under certain conditions and are primarily used in electronic devices to control the flow of electricity. Dielectrics are insulating materials that can be polarized by an electric field, but they do not conduct electricity. Therefore, the definition and characteristics of a conductor most accurately describe a material that facilitates the easy flow of electric charges.
