Electrical Insulators

Electricity can flow easily through some materials and less well through others.

Electrical insulators

Electrical insulators are materials do NOT allow electricity to flow through them.

Non-metals

Some non-metals are good electrical insulators. For example:
- Plastics.
- Rubber.
- Wood.

Electrical insulators at home

There are electrical insulators in your home.
The wires in your home are covered in plastic.
Plastic is an electrical insulator that prevents us from getting electric shocks.
