Conductors & Non-Conductors

The video explains the differences between conductors and non-conductors, focusing on their chemical structures and how they affect electrical conductivity. Metallic solids, like copper, are conductors due to their lattice structure and free-moving electrons. Superconductors, such as some pure metals and metal oxides, offer minimal resistance when supercooled. Non-metal conductors, like graphite, conduct electricity with more resistance. Insulators, including most nonmetals and solid ionic substances, have tightly bound electrons, preventing electrical flow. The video also discusses how an electric shock can occur despite the human body being an insulator.
