• Insulator 
• Resistance 
• Conductor 

Multiple Choice

A series circuit has ____ path(s) that the electric current can take. 

• One
• Two 
• Three 
• Four

Multiple Choice

This is an example of a _______ circuit

• open

• series

• parallel

• square

Multiple Choice

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 is divided between the three light bulbs.

Multiple Choice

What is the energy source for a circuit?

• Light bulb

• Battery

• Wire

• Switch

Multiple Choice

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.

Multiple Choice

__________ remains the same in a series circuit.

• Resistance

• Voltage

• Current

• Power

Multiple Choice

In parallel circuit, there are _________ pathways for charge to flow.

• One

• Two or more

• None

• Zero

Multiple Choice

In a parallel circuit, if we remove one of the light bulb, what will happen to the other light bulb?

• The other light bulb will stay on.

• The other light bulb will be off

• Both light bulb will be on

• Both light bulb will be off

Multiple Choice

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit

• series circuit

• parallel circuit

• open circuit

Multiple Choice

What is one problem with using a series circuit? 

• It has a lot of series. 

• If one light goes down, they all go down! 

• It doesn't work properly.

• There are no problems. 

Multiple Choice

What is a benefit of using a parallel circuit?  

• It gets confusing.

• There are no problems.

• If one light goes out, it does not affect the others. 

• If one light goes out, they all go out. 

Multiple Choice

If we add more light bulbs into a parallel circuit, how will the brightness of the bulbs change?

• It will get dimmer

• It will get brighter

• The brightness will stay the same

• None of the light bulb will be on
