Circuits
In this type of circuit, electricity has only one path to follow.
Series Circuit
These are materials through which an electric current can pass.
Conductors
This early scientist discovered electricity during a lightning storm.
Benjamin Franklin
These are temporary magnets, NOT permanent magnets.
Electromagnets
This it the flow of electricity along a pathway.
Current
In this type of circuit, electricity has more than one path to follow.
Parallel circuit
These are materials through which an electric current CANNOT pass.
Insulators
This man improved the light bulb.
Thomas Edison
This term means "to push away".
Repel
The pathway on which a current travels.
Circuit
This type of circuit is a complete circuit where everything is connected and electricity can easily flow through it.
Closed circuit
List three examples of conductors.
Nails, paperclips, aluminum foil, etc.
This man created the generator and electric motor.
Michael Faraday
This is the invisible force around every magnet.
A magnetic field
This is a material that cuts down the flow of current, but does not stop it.
This type of circuit is an incomplete circuit where there is some part that is not connected and electricity cannot flow through it.
Open circuit
List three examples of insulators.
Plastic, wood, rubber, etc.
This is energy associated with heat.
Thermal energy
Where is a permanent magnet the strongest?
At the poles (the ends)
This is static electricity in nature
Lightning
This is a device that is used to open and close a circuit easily without connecting and disconnecting the wires.
A switch
This is the build up of electrons on a surface.
Static Electricity
This is energy associated with motion.
Mechanical energy
Opposite poles of magnets do this.
Attract
Name the three objects you need to make a simple electromagnet.
Nail, Wire, Battery (Dry Cell)
