प्रश्न
Distinguish between conductors and insulators of electricity. Give two examples of each.
उत्तर
Conductors
- Conductors are those subs¬tances which allow electricity to flow through them.
- e.g. all metals, human body.
Insulators
Insulators are those which do not allow electricity to pass through them. –
e.g. wood, paper, glass.
