Fig. 050: a) Connect the connection lines of the solar module to the plug board.
b) The cables can be additionally secured with the plug pins.
Place the solar module so that sufciently bright light, preferably sunlight, falls onto
it.
If the sun does not shine during the experiments, you can replace it with
a bright desk lamp, e.g. with a halogen light bulb (at least 30 W). Energy
savings lamps and LED lamps are not suitable.
Now plug the connections of the red LED and the dropping resistor 100 Ω into the
plug board. The longer connection of the light-emitting diode is to be connected to
the +-»side«. Depending on the radiation intensity, the light-emitting diode will light
up more or less brightly. If the LED does not light up, either there is not enough
„light energy“ or the LED has been connected in the wrong polarity. If the light-
emitting diode ashes, you have accidentally used the ashing LED.
