Circuits

The flow of electricity through a conductor is called...

• resistance
• voltage
• current
• source of electric current

This measures the speed of the current in a circuit

• voltage
• ammeter
• switch
• resistance

What slows down the flow of electricity in a circuit?

• resistance
• voltage
• current
• source of electric current

Which circuit (s) are parallel?

• A
• A and B
• B and C
• C

Which one will still function if one light bulb goes out?

• A-Series
• B-Parallel
• A-Parallel
• B-Seriese

If I add more light bulbs to a series circuit what happens?

• The current speeds up and the lights get brighter
• The current slows down and the lights dim lower
• The current speeds up and the lights dim lower
• The current slows down and the lights get brighter

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

The equivalent resistance in this circuit is

• 100 ohms

• 450 ohms

• 400 ohms

• 30 ohms

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.
