100
Non moving electrical charges are what kind of electricity?
Static electricity
100
Describe what renewable energy sources are.
Come from resources that will naturally renew or recycle themselves
100
What does a circuit always need?
A power source like a battery with wires connected at the positive and negative ends
100
What is a series circuit?
Several components are one after the other without any branches
100
Give a definition of a insulator
A material that does not allow electricity to pass through them
200
Which Greek philosopher first observed static electricity?
Thales
200
Give three examples of renewable energy sources.
Tidal energy, Hydro energy, Wind energy
200
Describe an incomplete circuit
A circuit that is not continuously connected. There is a gap like a disconnected wire or an open switch
200
Describe a parallel circuit
Different components are connected on different branches of wire
200
Give a definition of a conductor
Material that allows electricity to pass through it easily
300
This type of electricity si described by moving electrical charges that move between objects in a controlled path.
Current electricity
300
Give an example of a non renewable energy source
Come from resources that will not renew or recycle themselves
300
Draw the symbols for the following parts of a circuit: battery, wire, bulb, switch (on), switch (off)
Use your notes to confirm
300
Draw a series circuit
Check your notes
300
Is a rubber band an insulator or conductor?
Insulator
400
The shocks from static electricity are caused by what?
Friction
400
Give three examples of non-renewable energy sources
Coal, Oil, natural gas, nuclear energy
400
Adding more batteries to a single bulb circuit will likely result in what?
A bulb lighting up brighter because more energy is being sent to the single bulb
400
Draw a parallel circuit
Check your notes
400
Is a key and insulator or conductor
Conductor
500
An electric shock from current electricity can be deadly. True or false?
True
500
Provide an advantage and a disadvantage of coal energy
Advantage: can be built near cities, creates a large amount of electricity, coal is the most abundant fuel on earth Disadvantage: Air pollution, expensive to set up, causes acid rain, adds to global warming
500
Adding more bulbs to a single battery circuit will result in what? Explain why.
The lights will be dimmer because the energy is being split between two things rather than one
500
Describe when parallel circuits are useful
They are useful when you want everything to work even if one component has failed like a string of Christmas wires
500
Explain why wires are covered in a plastic tube.
They are covered in a plastic tube so that we are protected from the electrical current running through them. plastic is an insulator so it allows the electricity to travel through the wire but keeps us safe from shock.
