200

• If there is a ____________ lights are able to work.                  

  What is a Closed Circuit?

300

• A current that only has one path to flow would be considered to be this kind of circuit.         

What is a Series Circuit?

400

• This provides two or more paths for electrons to flow.               

What is a Parallel Circuit?

500

• If your light is not working it is because there is an _____________.              

What is an Open Circuit?

Vocab 1

100

• If this is opened electron cannot flow through a circuit, however when it is closed they can.      

What is a Switch?

200

• The Unit that measures electrical current.       

What is Amperes?

300

What is a Generator?

400

• 
  
• If electrons are swiped by rubbing than they are transferred by _______________.        

What is Friction?

500

• Charges in an uncharged object are rearranged without direct contact with a charged object.

What is Induction?

Vocab 2

100

Substances that are magnetic all the time?                      

 What is a Permanent Magnet?

200

• This type of material allows electrons to flow through it easily.             

What is a Conductor?

300

• This describes the tendency of a material to oppose the flow of electrons.      

What is a Resistor?

400

• The electric charge only flows in one direction with this.            

What is Direct Current?

500

• Electrons are transferred by direct contact of an object.            

What is Conduction?

Voltage, Amp, Current

100

• The earth is surrounded by this.
