Electricity – Simple Circuits
Materials are either
A conductor allows electricity to pass through it. E.g. metals are good conductors
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…
