Multiple Choice

What type of circuit is this?

• series circuit

• parallel circuit

Multiple Choice

What type of circuit is this?

• Series Circuit

• Parallel Circuit

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.
