Light Intensity And Characteristics Of Photocells
Light Intensity Characteristics of Photocells
The photoelectric effect is defined as the emission of electrons from a material by visible light. The cadmium sulfide photocell is used to act as a conductor once exposed to light, allowing light to travel through. However it also acts as an electric resister (an opposition to a current flowing in a circuit) once not exposed to light. The photocell serves today's cause in a sufficient manner. It is used for a variety of reasons but it is mainly used as smoke detectors and other alarms. This proves that the photoelectric effect occurs in a CdS photocell.
Cadmium Sulfide is a metal that is formed along the earth's crust. Some characteristics of the sulfide are is that it has a low melting point, rapid electrical exchange, resists high temperatures, degrades plastics in UV rays, has different pigments, and has high electrical and thermal conductivity. Cadmium sulfide is contained within the photocell. It relates to the......
