Flow of Water

  • Water is stored in bucket
  • Gravity pulls water through pipe
  • Core concepts

– water pressure – size of the pipe – amount of water flow per time unit

More Pressure

  • Bucket filled twice as much
  • Double water pressure

⇒ Double water flow

Bigger Pipe

  • Pipe twice as big
  • Twice as much water in pipe

⇒ Double water flow

Electricity

  • Electrons are stored in battery
  • Electric field pulls electrons

through wire

  • Core concepts

– voltage = electron pressure – ampere = size of the pipe – watt = amount of electrons flow per time unit – watt hour = amount of electrons

  • 1 kWh costs about 10 cents
