Circuits Physics

How does a voltmeter meter is added in the circuit?

• Series

• Parallel

Name the component...

A series circuit has how many pathways for the electrons to flow?

• Two

• One

• Many

• Zero

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. 

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

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.
