Parallel and Series Circuits

Two types of Circuits

• ​There are two types of circuits:

• ​parallel: there are multiple pathways for electricity to travel

• ​series: there is only one pathway for electricity to travel

​Series Circuits

• ​In a series circuit, there is only one path for electricity to travel.

• ​If one part of the circuit stops working (the load, the wires, or the power source) the entire circuit stops working.

​Parallel Circuit

• ​In a parallel circuit, there is more than one pathway for electricity to flow.

• ​If one part of the parallel circuit stops working, the electricity will still flow.

Multiple Choice

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
• The battery will become stronger.

Multiple Choice

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.

Multiple Choice

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.
