The reasons for electrical conductivity are mentioned below:
Explanation:
- Metals can conduct electricity because the free electrons move and do not belong to a single atom. The free electrons start to move in the direction of the current.
- Ionic solids are able to conduct electricity when when they are dissolved in water or they are in melted. The ions are free to move in aqueous solution.
- The semi conductors also contain free electrons so that they can conduct electricity.
