Electricity and Magnetism – Notes
Electricity and Circuit – Electricity Conductors and Insulators
Materials that allow electricity to pass through them are called conductors.
Materials that do not allow electricity to pass through there are called insulators.
We need conducting materials to make electrical circuits.
Air is an insulator
All electrical appliances are covered with insulating materials to protect us from electric shocks.
