Fig.3.58: measuring the voltage of the electrolytic with a multimeter
3.8.5 The steam engine as a charging station for the torch.
Assembly of the experiment: we use the assembly of the second last
experiment. We plug in two white LEDs instead of the orange LED.
You can disconnect the crocodile clips after a short charging period through
the steam engine and generator.
Now both LEDs will shine for a while when you press the switch. Then you
can connect the bread board with the “LED torch” to the charging station
“steam engine” again.
It is amazing how long the LEDs are shining with this charge regarding to
the small storage capacity of the electrolytic.
