The teacher blew a circuit and the copier stopped!
Electricity provides power.

How does electricity even get here anyway?
Electricty is produced in power plants.
Fossil fuels, tides, wind, & nuclear sources can also be used to turn the turbines.
Solar skips that step
Electricty is the movement of electrons along a conductive path used to provide power for flashlights, copy machines, businesses & factories.
How does electricity get to my iPhone charger?
Electricity is produced when mechanical energy is turned into electrical energy by power plants using turbines & generators.
Circuits control the flow of electricty.
Close the switch to make the elctrons flow.
The voltage of the elctricity is stepped up by a transformer to be carried far away from plant by transmission lines. Another transformer is used near your house to step down the voltage to be carried by local telephone poles (or underground).
Conductors carry electric current well, while insulators do not.
Once the flow of electrons reaches a pole outside your house, it is stepped down again and fed into a meter on the side of your house. This meter measures how much electricity you use. It goes into a breakerbox that protects your circuits, appliances and electronics.
Switch turns on/off flow of electrons (toggle, touch) Load uses the flow to do work (light, heat, spin) Source where the electrons come from (battery, outlet, solar panel) Path conductive wire where electrons flow across
Metals make good conductive paths, wood and plastic do not. Many wires are covered in plastic which keep the electrons from flowing out. The copier is working! I fixed the circuit!
