Open Closed Circuit Parallel Series

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.

When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.

• parallel
• series
• open
• closed

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

What kind of circuit is this?

• series
• parallel

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.
