The experiment provides students with the opportunity to learn about a light dependent resistor (LDR), which is a resistor with particular characteristics which is often used in electronic circuits.

One item deals with „Technical application and vocational orientation“.

Information and ideas:
Additional task: Students can measure the resistance in the LDR using the digital multimeter; for example, measure resistance when the LDR is in full light, then measure resistance when the LDR is covered.
