Lesson 4 – Series and parallel – plan
• http://www.bbc.co.uk/education/clips/zpj34wx
How do you think these differences affect the current and potential difference in these circuits?
Learning Objectives
Describe what the difference is between a parallel and a series circuit
Describe how A and V vary in both circuits
Keywords
Parallel circuit Series Circuit CurrentPotential Difference
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
Lets have a look at what we are doing to day

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?
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.
