1. Series and Parallel Circuits
Answer the following questions:
Describe a series circuit.
Give one advantage to a series circuit.
Give two disadvantages to a series circuit.
Describe a parallel circuit
Give an advantage to a parallel circuit.
Give a disadvantage to a parallel circuit.
Which type of circuit is used in our homes.
Why is this type used?
Name the three types of energy that electrical energy can be converted into.
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?

2. Series and Parallel Circuits

3. 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

4. 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)

5. 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? + + +

6. 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

7. Predict, Test and Explain
How will the brightness of the bulbs change as we add more in parallel?
What does this imply about the current in the circuit? + + +
