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.

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

• increase
• decrease
• stay the same

The current going through the 45 ohm resistor is 

• 0.05 amps
• 0.2 amps
• 0.1 amps
• 5 amps

• 0 amps
• 9 amps

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit

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

• Bulbs are in parallel - Circuit X is brighter than Circuit Y
• Bulbs are in parallel - Circuit Y is brighter than Circuit X
• Bulbs are in series - Circuit X is brighter than Circuit Y
• Bulbs are in series - Circuit Y is brighter than Circuit X

This circuit does not work because…

• the bulbs are not connected properly
• two cells are not powerful enough
• there is a break in the circuit
• the cells are facing each other
