Gavin asked “Why does the energy flow through the wires?”
Tegan asked “How does electricity work?”
Hayden asked “How do batteries springs and wires make a complete circuit?”
So how does this compare with a modern day battery. lets have a look and think about Gavins question.
Hayden and Tegan. In the circuit below the energy flows around the circuit when the switch is closed. Why? What are wires made of? What is special? If the wires were plastic do you think electricity would be able to pass through it? Try and make your own circuits with different materials.
Electricity is linked to the passage of negatively charged electrons. These were very comfortable in the battery until it was connected to a circuit (a circuit is a continuous pathway) and the switch was closed. The circuit gave the electrons (negatively charged) a passage to the positively charged end of the battery. Electricity (electrons) flowed and accompanying the electrons was energy. Look at the Science Master Special on Energy and why not try the Circuit Quiz.
Do not play with mains electricity. It is very dangerous and could kill you.
