A diode that is sensitive to light. As light increases, the diode resistance drops. This can be used as a sensor in control circuitry that directs solar panels so they are always facing the sun. They also can be used to automatically turn on street lights, garden lights, among many other applications.

What type of diode produces an electrical response when subjected to light?
A photo diode
What is difference between a diode and a photo diode?
diodediode conducts by applying certain voltagephoto diodephoto diode conducts when it is exposed to sun light
Does electric current remain constant in a circuit?
No it depends on voltage and circuit resistance and other physical parameter which affect the properties of component used in circuitry like - temperature pressure humidity light(in light sensitive circuit- LDR photo diode,photo transistor,) and other.
Why photodiode works only in reverse bias not in forward bias?
The fractional change due to intensity on minority charge carriers is more than on majority charge carriers. When light is directly polarized it acts like a normal diode but when reverse polarized its current depends on the brightness (intensity of incident light).
Does zener diode works after breakdown voltage?
Yes. The intended use of a zener diode is to be reverse biased at the breakdown voltage. In this mode, the zener has high slope in the current to voltage curve, making it a good choice for voltage regulation.
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
What is the different between photo-diode and LED?
A Photo-diode is used to receive light. whereas the L.E.D. is a Light Emitting Diode.
What is the difference between potentiometer and light-sensitive diode?
potentiometer is not sensitive to lightpotentiometer has three terminals, diode has two
A silicon avalanche photo diode is fabricated by what process?
A silicon avalanche photo diode is fabricated by the process called impact ionization.
Television signals are converted into light signals by?
Laser Diode. photo diode
What type of diode produces an electrical response when subjected to light?
A photo diode
How do you use ir led?
IR LED will be having connecting leads same as ordinary LED. When ever we use IR LED, which works like a transmitter we have to connect a photo diode as a receiver (very near to IR LED). So as we know IR LED keeps on emitting IR radiations photo diode will keeps on receiving, it in a reflecting surface. In case if the surface not reflect IR radiation(Black surface obsorbs IR). the input to the photo diode becomes nil, and photo diode wont work and hence the circuit. inform.mayaprasad@gmail.com
What is a photodiac?
a bidirectional light-sensitive avalanche diode
What is difference between a diode and a photo diode?

Is the 2N5777 photo diode an APD or a pin diode?
The 2N5777 is a Darlington silicon NPN photo detector, or, if you prefer a photoDarlington. A link is provided to a bit of data on this device.
What is dark current in photo diode?
yo mamas ass
If photo sensitive is for light what is the term for heat sensitive?
thermal.
