ملخص الدرس

This lesson categorizes physical materials into electrical conductors and insulators based on atomic electron mobility. It explains why metals (copper, aluminum) conduct electricity via free electrons, why non-metals (rubber, plastic, glass) act as insulators, and details real-world applications in wire construction, tool insulation, and electrical shock prevention.

هتتعلم إيه فى الدرس ده

• Conductors allow electric charges to flow easily due to free electrons.
• Metals (copper, aluminum, iron) and saltwater are excellent conductors.
• Insulators (rubber, plastic, glass, wood) prevent electric current flow.
• Electrical cables and tools combine conductors internally for current transfer with insulators externally for safety.
