Conductors are materials that allow electricity to flow freely through them. They are typically made of metals such as copper, aluminum, and gold. On the other hand, insulators are materials that do not allow electricity to flow through them easily. Examples of insulators include rubber, glass, and plastic. Conductors are often used in electrical wiring, while insulators are used to protect people and buildings from electrical currents. It is important to use the appropriate materials for conducting or insulating electricity to ensure safety and efficiency.
