In 3–5 sentences, explain why electrical wires are often constructed from metal coated with rubber, and how that is similar to metal pans having rubber or plastic handles.(4 points)
Electrical wires are often constructed from metal coated with rubber to provide insulation and protect against electrical shocks. Rubber is an excellent insulator, preventing the flow of electricity through the metal core of the wire. Similarly, metal pans having rubber or plastic handles provide insulation from the heat generated during cooking to prevent burns. In both cases, the rubber or plastic coating acts as a protective layer, ensuring safety and preventing potential accidents.
