Form 2 Chapter 7.2 (Series and Parallel Circuits)

This is an example of a _______ circuit

• open
• series
• parallel
• square

This is an example of a ______ circuit

• Series
• Parallel
• Open
• Dihexihedral

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 circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit
• series circuit
• parallel circuit
• open circuit

As resistors are added in series to a circuit, the total resistance will...

• increase
• decrease
• stay the same

As the resistance of a circuit increases, the current will...

• increase
• decrease
• stay the same

What is the definition of electrical current?

• The opposition to the flow of electrons

• The rate of flow of charge

• The work done on each coulomb of charge

• Electrons moving around

Does this statement best describe a parallel or a series circuit.
 
When more light bulbs are added they all remain bright. 

• Parallel circuit
• Series circuit

• Series circuit - Bulbs are lit
• Series circuit - Bulbs are off
• Parallel circuit - Bulbs are lit
• Parallel circuit - Bulbs are off

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.
