Electricity – Simple Circuits

Materials are either


A conductor allows electricity to pass through it. E.g. metals are good conductors

 or Insulators

An insulator does not allow electricty to pass through it. E.g. wood

A good conductor is a bad insulator.

A bad conductor is a good insulator.

To test whether a material is a conductor or an insulator you need to use a complete circuit.

Watch the video below to see some different materials being tested…
