| Definition | Materials that allow the free flow of electric current or heat. | Materials that resist the flow of electric current or heat. |
| Electrical Conductivity | High electrical conductivity. | Low electrical conductivity. |
| Thermal Conductivity | Good conductors of heat (e.g., metals like copper). | Poor conductors of heat (e.g., wood, plastic). |
| Examples | Copper, silver, aluminum, gold. | Rubber, glass, wood, plastic. |
| Electron Movement | Electrons are free to move within the material. | Electrons are tightly bound to atoms and cannot move freely. |
| Charge Distribution | Charge spreads evenly across the surface of the material. | Charge remains localized and does not distribute. |
| Use in Electrical Circuits | Used to make wires and connections for transmitting electricity. | Used to insulate wires and prevent electric shocks. |
| Effect of Temperature | Resistance increases with an increase in temperature. | Resistance typically remains unaffected by temperature. |
| Magnetic Properties | Can exhibit magnetic effects in some cases (e.g., ferromagnetic materials). | Do not exhibit significant magnetic effects. |
| Applications | Electrical wiring, heat sinks, cookware. | Insulation in electrical appliances, handles of tools, safety equipment. |
| Role in Energy Transfer | Facilitate energy transfer. | Prevent energy transfer. |
| Atomic Structure | Contains loosely bound electrons that can move freely. | Contains tightly bound electrons that cannot move. |
