• increase
• decrease
• stay the same

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.

• True.

• False.

Which statement is true?

• The light bulb will light up because the circuit is complete.

• The light bulb will light up because the circuit is broken.

• The light bulb will not light up because the circuit is complete.

• The light bulb will not light up because the circuit is open.

What type of circuit is the image showing?

• Parallel

• Series

• No circuit

How will increasing the amount of resistance in a circuit affect the current if the voltage remains constant?

• It will increase

• It will not change

• It will decrease

• It will cease

If a light bulb burns out in a series circuit, the total current

• remains unchanged

• becomes zero

• is increased a little

• is decreased a little
