Photoelectric Cell
Photoelectric Cell. A photoelectric cell, also called sometimes a phototube, electron tube, or electric eye, is an electronic device that is sensitive to incident radiation, especially visible light, which is used to generate or control an output of electric current.During the latter half of the nineteenth century, many scientists and engineers …
Photoelectric Effect in Photocells: Application & Physics
Photoelectric Effect in Photocells - Key takeaways. Photoelectric Effect in Photocells: In photocells, photons striking the surface can impart sufficient energy to electrons to overcome the material''s work function, which is the basic energy required to get an electron moving. The light''s intensity influences the number of emitted electrons ...
Photoelectric Effect: Explanation & Applications | Live …
Applications. While the description of the photoelectric effect sounds highly theoretical, there are many practical applications of its work. Britannica describes a few:
Uses of Photocells
Photocells are semiconductors that are light detectors. They are essentially light dependent resistors, because they have an output that is proportional to the amount of light that falls upon them. Because of this effect, they are also known as photoresistorsors or light dependent resistors (LDRs).
Photoelectric cell: Construction, working and applications
Applications of the Photoelectric Cell: The photoelectric cell is used in the reproduction of sound which is recorded on a movie film. The photoelectric cell is used in exposure meter. The exposure meter is used along with a camera to know the correct time of exposure for having a good photograph.
