1. Lesson 4 – Series and parallel – plan

2. How do you think these differences affect the current and potential difference in these circuits?

3. Learning Objectives Keywords
Parallel circuit
Series Circuit
Current
Potential Difference
Describe what the difference is between a parallel and a series circuit Describe how A and V vary in both circuits

4. What do we know already? How Do you measure current?
What is the charge of a Proton, Electron, Neutron?
How do we measure potential difference?
Amp meter in Amps
Positive, negative, and neutral
Voltmeter in volts

5. Lets have a look at what we are doing to day

6. Please Answer
What are the differences between series and parallel circuits?
How does the current change between a series and a parallel circuit?
How does the potential difference differ between a series and a parallel circuit?
Can you explain your observations on current and potential difference?

7. This lesson I have learnt:
circuits can be in series or in parallel  
in a series circuit, the current is the same everywhere  
in a parallel circuit, the current in each branch is the same but add together to make the total current of the circuit.
