converted into.
10) Its Christmas, and as you pass by a house lined with lights you
notice that one of them has a bulb burned out but the rest are
working fine. What can you tell about the string of lights?

Circuits
In order for electricity to flow we need
Power source
Closed circuit
There are two type of circuits we will
explore
Series circuit
Parallel circuit
Series Circuit
In a series circuit there is only one path for the electrons to
flow
In other words all the components are in series with each
other
Because there is only one path each charge will go through
each resistor (electrical device)
Predict, Test and Explain
• How will the brightness of the bulbs change as we
add more in series?

• What does this imply about the current in the
circuit?
Parallel Circuit
In a Parallel circuit there are multiple pathways for charge to
flow
Each device is placed on it’s own separate branch
Current goes through each of the branches at the same time
Predict, Test and Explain
• How will the brightness of the bulbs change as we
add more in parallel?
