6th Six Weeks Review

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 is divided between the three light bulbs.

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. 

In a parallel circuit if one of the light bulbs burns out the rest _________.

• stop the flow of electricity
•  can still light up
•  will go out
• of the light bulbs burn out also

What is current measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is resistance measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is Resistance?

• The flow of electrons
• Electric potential difference
• A battery
• The ability to reduce the flow of electrons

What is the Voltage of a circuit that has a resistance of 5 Ω and a current of 2 A?

• 25 V
• 10 V
• 2.5 V
• 0.4 V
