• False 
• True 

What is the resistance in R₂?

• 12Ω
• 28Ω
• 7Ω
• 10Ω

What is the current through R₁?

• 2A
• 4.5A
• 1.5A
• 0.5A

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.

What type of circuit is show in the image?

• Series Circuit
• Parallel Circuit

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current has more than one path to flow through

What is a Parallel circuit? 

• Has only one path 
• Has more than one path 
• Allows energy to travel through easily 
• Has only one light bulb

What is a switch's function in a circuit?

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

This instrument can be used to see if materials conduct electricity.  Which of these groups contains items that could all conduct electricity to complete the circuit?

• rubber ball, plastic comb, nail
• paper clip, penny, screw
• cork, dollar bill, tweezers
• pencil, eraser, spoon
