In school you will have learned about electricity, switches, batteries and bulbs. It is very useful. Electricity powers bulbs and keeps our lights on. It runs our televisions and computers, and makes our fridges work. Electricity can be turned on and off by switches. Some things need batteries to work. Batteries store energy. But the energy in batteries does run out. These questions are about using electricity.

A flat battery has lost all its stored energy
|
Cell phone batteries are very small, but they store energy - just like other batteries
