connection cable towards the insulation and then stick all into the clip.
This connection can maintain like this in most of the following
experiments.
Fig.3.20:a) connection of generator cable and crocodile clips, b) detail,
how to put in the cable to provide a stable contact.
Do not connect the generator to the steam engine for the first experiments!
3.3 First experiments with the generator
Components like before, 1 orange LED added
For the first experiment with generator (not connected to the steam engine)
you mount a circuit with an orange LED. The longer wire of the LED is the
positive pole and shows into the direction where the red connection of the
generator is connected. When all parts are assembled one turns the axis of
the generator (together with the belt wheel) forward and backward, holding
it between thumb and index finger. In one direction the LED will flash, in
the other direction she does not shine.
