Show transcript
A loop of connected electrical components that goes from one side of a cell to the other is called a series circuit.
When making a series circuit, connect the battery last. Disconnect it first when taking the circuit apart.
Switches are inputs in electrical circuits.
Simple switches can be made with split pins, card and paper clips.
Zinc–carbon cells and batteries are safer to use in schools, as they are less likely to short-circuit.
