Photoresistors also known as light dependent resistor (LDR) are used to increase light intensity by decreasing resistance. This is applied to camera lights, street lights, solar street lamps.

Which model of light best explains interference phenomena?
Albert Einstein in his 1905 paper on the photoelectric effect. Summarize as saying that when a photon strikes a metal it will cause electron flow. Wilhelm Hallwachs made the first photocells. An alloy of metals made the first photoresistors. Then solar cells. Albert did not "invent" the effect, it was already known, but he EXPLAINED how it works.

What does a photoresistor do?
What does a photoresistor do ?Photoresistors (also often called phototransistorsor CdS photoconductive photocells; use 'photocell' for digikey) are simple resistors that altar resistancedepending on the amount of light place over them.
Which isotopes are used in smoke detectors?
Americium (241) is used in smoke detectors that use "ionizing radiation" to detect changes in the air. Other types of detectors use photo-electric sensors based upon a variety of photo-sensitive chemicals.
What are the disadvantages of phototransistor?
Phototransistors have several important advantages that separate them from other optical sensors. For example, phototransistors produce a higher current than photodiodes while also being able to produce a voltage, something that photoresistors cannot do. Phototransistors are very fast and are capable of providing nearly instantaneous output. Phototransistors are relatively inexpensive, simple, and small enough to fit several of them onto a single integrated computer chip.
How did Geoffrey Rose invent the laser harp?
Hi, I am Geoffrey Rose.The laser harp was inspired by the theremin, which I had built from a kit many years before.In 1976 I designed the first harp to create a digital theremin.I used a 5mw laser divided into 10 beams, which created a 5 X 5 matrix of intersecting beams in an octagonal frame.There is a pic on Laser Spectacles website.By using photoresistors at the end of the beam paths and by using AND gates diodes, 25 different sounds were produced by a synthesiser in circuit with the resistors...easy...

When to use me and you or you and i?
If you would use 'I' in the singular, then use 'you and I'. If you would use 'me', then use 'you and me'.
