Anything which supplies electricity is also supplying energy. So cells, batteries, generators etc. all transfer energy to components in the circuit.

MOTION: Motors    LIGHT: Lightbulbs    HEAT: Hair dryers/kettles    SOUND: Speakers

Resistors and heat

  • Whenever a current flows through anything with electrical resistance then electrical energy is converted into heat energy.
  • The more current that flows, the more heat is produced.
  • A bigger voltage means more heating because it pushes more current through.
  • Filament bulbs work by passing a…
