Series and Parallel Circuits Practice

The electric current has only one path to follow to and from the energy source.

• Parallel Circuit

• Open Circuit

• Series Circuit

• Closed Circuit

Contains two or more paths for electric charges to follow.

• Closed Circuit

• Series Circuit

• Open Circuit

• Parallel Circuit

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.

What is a Parallel circuit? 

• Has only one path 

• Has more than one path 

• Allows energy to travel through easily 

When one bulb in a series circuit containing several light bulbs burn out:

• the other bulbs burn brighter.

• nothing changes in the rest of the circuit.

• none of the other bulbs will light up.

How many light bulbs would be ON if the wire of this circuit was cut where the scissors are?

• 1

• 3

• 2

• 0

If the light bulb in the middle burned out, what would happen to the other two?

• The light bulb to the left would stay lit, but the one to the right would turn off.

• They would both stay lit.

• The light bulb to the right would stay lit, but the one to the left would turn off.

• They would both turn off.

How many light bulbs would be ON if the wire of this circuit was cut where the scissors are?

• 1

• 3

• 2

• 0

A student builds a circuit made up of a battery, two lightbulbs, and a switch, as shown below. What will the student most likely observe in this circuit?

• Lightbulb 1 and Lightbulb 2 will both be on.

• Lightbulb 1 will be off, but Lightbulb 2 will be on.

• Lightbulb 1 and Lightbulb 2 will both be off.

• Lightbulb 1 will be on, but Lightbulb 2 will be off.

If you disconnected the wire from only the top bulb holder, what would happen? Select all correct answers.

• The bottom bulb would stay lit.

• The bottom bulb would go out.

• The top bulb would go out.

• The top bulb would stay lit.
