An electrical insulator is a material that resists the flow of electric current, used to prevent electrical leakage and ensure safety. Common insulators include rubber, plastic, ceramic, and glass. In electrical systems, they are used to coat wires, line the inside of electrical boxes, and support power lines, preventing unintended contact with conductive materials. Their function is critical for isolating electrical components and preventing short circuits.
