Electricity & Circuits

Electricity: movement of electrons

1. Moving a magnet relative and metal (copper) wire creates a flow of electrons

   • metal must conductive

   • electrons move via the wire, based on magnetic

2. Circuit: a place for electrons to go, a path for them to follow and a reason to move

   • destination: battery

   • path: wire, conductors, low or high resistance (depth of width & material)

     • low = gases

     • high = light bulb filament

     • resistance = some electricity is lost to hear, the more resistance

   • flowing electrons: current, amperage

     • motor is the release of a turbine and generator

   • rotary motion: motor & magnet in a circle

     • motor = reverse gear, magnet = moving electrons that push a magnet

   • utilize electricity in reverse to generate

   • renewable = direct turn of a turbine instead of using a heat source for steam
