Q

(1.1.10.1.1-2) What is a common type of protective covering used on electrical conductors?

🔍 Key Concepts

• Materials commonly used as insulation on electrical wiring • Properties needed for a safe protective covering on conductors (flexible, non-conductive, heat-resistant) • Difference between insulating materials and metallic sheathing

💭 Think About

• Which option lists materials that are good electrical insulators, not conductors? • Which materials would realistically be found on everyday electrical cords, appliance wires, and extension cords? • Would a common protective covering be made of a metal or a non-metal if the goal is to prevent shock and short circuits?

✅ Before You Answer

• Confirm which choices are metals vs non-metals • Ask yourself which option matches what you actually see on typical power cords and household wiring • Eliminate any material that would conduct electricity rather than block it
