6 FAQs about [Photocell as a measuring element]

What is a device used for measuring a response of photocell?

Answer: A device used for measuring a response of photocell is called- a photoelectric cell. Explanation: A photocell or a photoconductive cell is a solid-state electronic device used to detect and measure light and radiations. A device that detects light.

What is a photoelectric cell?

photoelectric cell (photocell) Device that produces electricity when light shines on it. It used to be an electron tube with a photosensitive cathode, but nearly all modern photocells are made using two electrodes separated by light-sensitive semiconductor material.

Which element is used in a photoelectric cell?

Photo electric cell – A device containing a photoelectric metal which. produces an electrical current when struck by light is called a photo. electric cell. Which element is used in photocell? Caesium (Cesium) is widely and commonly used in photoelectric cells because it can easily convert sunlight into electricity.

How do photocells work?

When light photons fall on it, they force electrons to leap out of it and these are promptly attracted to the positive terminal, which collects them and channels them into a circuit, producing electric power. This basic design is called a photoemissive cell or phototube. Where are photocells used?

Who invented photoelectric cell?

In the year 1883, the inventor from America namely Charles Fritts developed a functional photoelectric cell. In the same year, Paul an engineer from Germany utilized the photocell in his observation called Nipkow’s disk.

What is a photocell?

A photocell is a technological application of the photoelectric effect. A photocell consists of a semi-cylindrical photo-sensitive metal plate C (emitter) and a wire loop A (collector) supported in an evacuated glass or quartz bulb.
