Physics: Edexcel IGCSE, topic 2.2.4
Electrical Conductors and Insulators
Some materials conduct electricity and others do not.

Electrical conductors
- An electrical conductor is material that allows electric currents (flow of electric charges) to pass through it.
- All metals are electrical conductors.

Electrical insulators
- An electrical insulator is a material that doesn’t allow electric currents (flow of electric charges) to pass through it.
- Plastic and glass are electrical insulators.
