Negatively charged particles called electrons move from one material to the other. The material that loses electrons becomes positively charged. The material that gains electrons becomes negatively charged.
1 of 12
What would happen if two positively charged objects were brought next to eachother?
Repel eachother, go in the opposite direction.
2 of 12
Describe what happens when a charged balloon is brought close to a wall.
They are oppositely charged, therefore the balloon sticks to the wall.
3 of 12
Describe why is a combe is able to pick up small pieces of paper.
The combe is negatively charged whilst the paper is positively charged, therefore they are attracted.
4 of 12
Describe how lightening is formed.
Lightening is an electric current caused by collisions in the clouds.

Why do you sometimes get electric shocks when you touch everyday items
You can get an electrostatic stock from charged items.
6 of 12
Explain the purpose of Earthing an appliance
For safety so no electric shocks occur.
7 of 12
Explain why static electricity is a potential danger when refuelling aircraft?
When a aircraft is refuelled, static builds up therefore this could cause sparks.
8 of 12
Define an electrical current and state what this is in metals.
Flow of electrical charge. When electrons flow through conductors such as a metal wire.
9 of 12
What does a ammeter measure?
Electrical current in a circuit, measured in amps.
10 of 12
What does a voltmeter measure?
Electrical potential differences between two points in a circuit, measured in volts.
11 of 12
What will happen if the potential difference increases in the current?
The current increases.
