Electricity Facts
100
A material that allows electricity to flow through it easily.
What is a conductor?
100
A source of electricity, a pathway for the electrons to flow through, and an electrical device to operate.
What are the three components of every complete circuit?
100
The flow of electrons along a pathway.
What is current electricity?
100
A negatively charged particle that forms part of an atom
What is an electron?
200
A material that does not allow electricity to flow through it easily.
What is an insulator?
200
A circuit that has only one pathway for the current to flow through.
What is a series circuit?
200
A device that allows you to control the flow of electric current.
What is a switch?
200
A battery or generator
What is a source of electricity?
300
A metal rod, water, copper, YOU!
What is are some examples of conductors?
300
A circuit that has more than one pathway for the current to flow through.
What is a parallel circuit?
300
An electric current that flows in only one direction
What is a direct current?
300
A hairdryer, a TV, a computer etc.
Which devices are operated using electric current?
400
wood, rubber, air
What are three examples of insulators?
400
The circuit is complete and electric current can flow along the pathway (the switch is on).
What is a closed circuit?
400
The push the batteries give to the electrons to move the electrons along a circuit.
What is voltage?
400
It converts chemical energy to electrical energy
How does a battery work?
500
The lead inside of the pencil
What part of a pencil conducts electricity?
500
The circuit is incomplete and electric current cannot flow along the pathway (the switch is off).
What is an open circuit?
500
The chemical mixture that is inside batteries
What is an electrolyte?
