Current Electricity and Circuits

Which best describes a parallel circuit?

• Electricity flows along one pathway.
• The flow of electricity comes from one source. 
• Electricity flows along more than one pathway. 
• The flow of electricity comes from more than one source. 

What is one problem with using a series circuit? 

• It has a lot of series. 
• If one bulb goes out, they all go out! 
• It doesn't work properly.
• There are no problems. 

A material in which electrons are not able to move easily is a(n) ______________________.

• circuit 
• insulator 
• resistance 
• conductor

What kind of circuit is this?

• series
• parallel

What is a switch's function in a circuit?

• to make the current hotter or colder
• to turn on and off the flow of current
• it is the pathway through which current flows
• to add more power to the circuit

The path through which electricity flows is called a _________.

• trail
• circuit
• receiver
• power source

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.

If you increase the voltage of the source in a  parallel circuit, what happens?

• Current decreases
• Current increases
• Electrons disappear
• Bulbs get dimmer

If you have a 3 bulb series circuit, what will happen if one of your light bulbs goes out?

• Bulbs get brighter
• Bulbs get dimmer
• Bulbs go out
• Nothing happens

If you add a second battery to your series circuit, what will happen to the current in your circuit?

• Decrease
• Increase
• Stay the same
