Distinguish between conductors and insulators.
Conductors | Insulators |
---|---|
1. Substances which allow electricity to pass through them are known as conductors. | 1. Substances that do not allow electricity to pass through them are known as insulators. |
2. They have free electrons that can move and carry a current. | 2. They do not have free electrons due to which they cannot carry a current. |
3. When a charge is given to a conductor, it spreads evenly on its body. | 3. When a charge is given to an insulator, it stays at the same place. |
4. Examples: metals, acid-mixed water, salty water, and alkali solutions. | 5. Examples: fur, glass, cotton, silk, wood, ebonite, and amber. |
