100
Material in which electric charges cannot flow easily
What is insulator

The charge of a proton
What is positive
200
The charge of an electron
What is negative
200
The charge of a neutron
What is neutral
200
A complete unbroken path through which electric charges can flow
What is electric circuit
200
The transfer of electrons by rubbing
What is friction
300
The disadvantage of using a fuse
What is you have to replace it when it "blows" (melts)
300
The severity of an electric shock depends on the amount of
What is current
300
An electric current will always follow the path of ______ __________
What is least resistance
300
The transfer of electrons by direct contact
What is conduction
300
The transfer of electrons by the electric fields (does not have to touch)
What is induction
400
An instrument that can detect the presence of an electric charge
What is electroscope
400
A device that creates a potential difference in an electric circuit
What is voltage source
400
The law that says charges are not created or destroyed
What is Law of Conservation
400
Clothes in a dryer acquire _________ cling by __________
What is static, friction
400
If you acquire a negative charge from walking across a carpet then touch a doorknob and receive a shock your charge is then electrically __________
What is neutral
500
The strength of the electric field of a charged particle becomes greater as the distance from the particle ___________
What is decreases
500
A circuit is electrically ________ if it can carry the current from a short circuit to earth
What is grounded
500
How conduction and induction are alike and how they are different
What is alike: there is a transfer of electrons... different: conduction is by direct contact and induction is transferred by the electric field, not direct contact
500
How a fuse protects against a short circuit
What is a fuse has a thin strip of metal that will melt if too many electrical appliances are plugged in at the same time and it gets too hot. The strip melting will stop the current so a fire doesn't start.
500
How lightening is formed
What is water droplets swirl around and create friction which causes the protons to go to the top of the cloud and electrons to the bottom of the cloud - then there is static discharge from the electrons in the cloud to the protons in the ground.
