Description

The subject of the experiment P4.1.2.4 is the characteristic of a light-dependent resistor (LDR). Its resistance varies from approx. 100 Ω to approx. 10 MΩ, depending on the brightness. The resistance is measured as a function of the distance from an incandescent lamp which illuminates the light-dependent resistor.
