Question
Differentiate between conductors and insulators.
Advertisements
Solution
| Sr. No. | Conductors | Insulators |
| 1. | Those substances through which electricity can flow are called conductors. | Those substances through which electricity cannot flow are called insulators. |
| 2. | Electrical resistances of conductors are very low. | Electrical resistances of insulators are infinitely very high. |
| 3. | They contain a large number of free electrons. | They do not contain free electrons. |
| 4. | Generally, metals are conductors. E.g., silver, copper, aluminium. | Generally, non-metals are insulators. E.g., wood, rubber, plastic. |
