Current and Circuits Review

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 kind of circuit is this?

• series
• parallel

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

In a Series circuit the more lightbulbs you add the brighter they get 

• False 
• True 

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

Find the voltage across R_1. (Check the resistance units)

• 12 V
• 4V
• 3V
• 2K

In order for a circuit to work you need to have

• A voltage source
• A complete pathway with no breaks in the circuit
• A resistor
• A voltage source and a complete pathway with no breaks in the circuit
