Classifying materials as Conductors and Non-conductors of electricity.
The ability to conduct electricity is called conductivity.
Some materials allow electricity to flow easily through them. These materials are
called conductors of electricity.
Examples of conductors of electricity are:
Copper wire.
Aluminum foil.
Iron
Carbon
Other materials do not allow electricity to flow through them. These materials are
called non-conductors of electricity.
They are also known as insulators.
Examples of insulators include:
Plastics.
Glass.
Cloth.
Threads.
Rubber.
Paper.
Stone.
Dry wood.
Mattress.
Sisal.
Dry sponge
