Electricity
Electricity is a very useful way of moving energy from one place to another. Almost everything we do relies on electricity

Conductor
Something like metal which allows electricity to pass through it
3 of 20
Insulator
Something that doesn't allow electricity to pass through such as a rubber or pencil
4 of 20
Switch
Something that completes an electrical circuit
5 of 20
ammeter
A device that tells us the electrical current
6 of 20
Component
