Electronics Fundamentals Circuits, Devices and Applications

A cadmium sulfide cell (CdS cell) is a photosensitive resistor that changes resistance when light strikes it. It is used in applications such as turning on lights at dusk. You could monitor the resistance indirectly from an ammeter when the cell is in an active circuit with the setup shown in Figure 12. What resistance is implied by the readings shown?
