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

“

”

again.

It is amazing how long the LEDs are shining with this charge regarding to
the small storage capacity of the electrolytic.
