What is any material that easily conducts electricity called?

The term for a material that easily conducts electricity is "conductor." Conductors, such as metals like copper and aluminum, have free electrons that allow electrical current to flow through them with minimal resistance. This property makes them ideal for use in electrical wiring and various applications where efficient electricity transfer is needed. In contrast, materials that do not conduct electricity well, such as rubber or glass, are referred to as insulators, which serve to protect us from electrical currents. Semiconductors are materials that have conductivity between conductors and insulators and are crucial in electronic devices, while resistors are components used to limit the flow of current in a circuit. Therefore, the focus on conductors highlights the fundamental role they play in the movement of electrical energy.
