What happen to the collector voltage, if the emitter resistor is removed and connect directly the emitter junction to the ground? What happen to the collector voltage if the 39kΩ resistor is disconnected (open)? If the 1kΩ resistor is remove and connect directly the emitter junction to the ground, what happen to the voltage collector?

Photoconductive Cell

Photoconductive cells are light-sensitive resistors in which resistance is inversely proportionated to light intensity when illuminated. These devices consist of a thin single-crystal or polycrystalline film of composite semiconductor materials. Cadmium sulfide (CdS) is used to make the most commercially available photoconductive particles which are sensitive to light in the visible spectrum. Other less commonly used substances respond to infrared light, but not to the visible spectrum. Such substances are lead sulfide (PbS), lead selenide (PbSe), and lead telluride (PbTe), and so on.
