Investigating wind turbines


  • Model wind turbine.
  • Clamp stands
  • Hair drier
  • Metre rule
  • Voltmeter (with mV range)


  1. Position the hair drier and turbine at the same height.
  2. Connect the voltmeter to the turbine.
  3. Use the Metre rule to position the hair drier 10 cm from the turbine.
  4. Switch on the hair drier and measure the voltage output of the turbine.
  5. Repeat this increasing the distance between the turbine and the hair drier by 10 cm each time.
  6. You may want to repeat each reading twice in order to calculate mean values.
