Year 9 Physics Quiz

Electricity is created...

• from electrons orbiting the nucleus

• from free-moving electrons

• from electrical potential energy

• from a wire

The two types of electricity are...

• Static Electricity and Current Electricity

• Static electricity and Kinetic Electricity

• Current Electricity and Kinetic Electricity

• Series electricity and Parallel electricity

Static Electricity is....

• an imbalance of charge due to friction between two conductors

• charges flowing through a person, causing them to get shocked

• an imbalance of charge due to friction between two insulators

• charges flowing through the carpet, causing people to get shocked when they step on it

Current Electricity...

• is the movement of electrons through a wire due to an energy source

• the rate of flow of electrons

• is the movement of protons through a wire due to an energy source

• the rate of flow of protons

Lightning is an example of

• Static electricity

• Current electricity

• Kinetic electricity

• Static energy

What is current?

• Electrons

• The flow of electrons

• The flow of protons

• The rate of flow of electrons

What are the two types of current?

• Straight current and bendy current

• Water current and currant

• Alternating current and direct current

• Alternator current and dynamo current

What is direct current?

• Current flowing in one direction

• Current flowing in every direction

• Current switching direction every second

• Current going directly through the wire

What is alternating current?

• Current going in the same direction

• Current swapping its direction every second

• Current alternating between protons and electrons

• Current changing it's strength

If there are more electrons moving or if the electrons are moving faster, the current will be...

• higher

• lower
