Beschreibung:
This experiment builds upon the learning of experiment 7.3, properties and function
of a transistor. A dark detector is a good first example of an electronic circuit, where
the input signal of the LDR operates an output (LED).
One item deals with „Technical application and vocational orientation“.
Information and ideas:
Depending on the LDR, the circuit functions slightly differently, i.e. you need to cover more or less of the LDR to switch on the transistor (LED). Also note that changing the 10 kΩ resistor to a different value will change the function of the circuit.
