Here you find once more the colours and values of the resistors listed and
the sequence of their use within the experiment.
Prepare the resistors before starting the engine and then you can stick them
into the bread board while the engine is running. You have a little more than
5 minutes to run the experiment if you take 2 dry spirit tablets and the
according amount of water. The orange LED will show you optically
whether the voltage of the generator is dropping or continuous. Wait till the
rotational speed of the steam engine has established and the LED is
continuously shining and only then start with the experiment.
