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

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.
