Series and Parallel

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. 

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. 

If the reading of A₁ is 0.3 A, what is the reading of ammeter A₂?

• 0.1 A

• 0.2 A

• 0.3 A

• 0.4 A

In which of these two circuits is the current the same at all points?

• A

• B

what is the current at point a?

• 0.4A

• 0.2A

• 0.1A

• 0A

A parallel circuit is set up using 3 similar lightbulbs as shown in the diagram. If the ammeter reading of A₃ is 0.2 A, what is the reading of Ammeter A₁ is _________ A

• 0.1 A

• 0.2 A

• 0.4 A

• 0.6 A

What is wrong with this circuit diagram?

• There is only one cell

• A ammeter should be connected in parallel

• The ammeter should be connected in series
