Electric Circuits

If lamp 1 is unscrewed from its holder, what will happen to lamp 2?

• It will get brighter

• It will stay the same brightness

• It will go out

• Nothing will happen

Why is a bulb brighter when it is powered by two batteries rather than one?

• Because the flow of electricity in the circuit is less

• Because the flow of electricity in the circuit is the same

• Because the flow of electricity in the circuit is greater

• Because the flow of electricity will go backward

If lamp 2 is unscrewed from its holder, what will happen to lamp1?

• It will stay lit

• It will go out

• It will get dimmer

• It will dissapear

A material that does NOT let electricity pass through it is called ...

• An electrical conductor

• An electrical insulator

• An electrical source

• An electric appliance

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.

This is the symbol for a _____?

This is the symbol for a _____?

• an AC current source
• a DC current source
• a battery
• a single cell

This type of circuit only has one path for current to flow. 

• series
• parallel
• combination
• split

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 goes down, they all go down! 
• It doesn't work properly.
• There are no problems.
