What is the conclusion of Zener diode experiment?

Conclusion. The Zener diode, with its accurate and specific reverse breakdown voltage, allows for a simple, inexpensive voltage regulator. Combined with the right resistor, fine control over both the voltage and the supply current can be attained.

What is the most important characteristic of a diode?

In an ideal diode, current flows freely through the device when forward bias, having no resistance. This is ideally what should happen, or what we would want to happen, but this is not what will happen. In an ideal diode, there would be no voltage drop across it when forward biased.

What happens if Zener diode is forward biased?

When forward biased voltage is applied to the zener diode, it works like a normal diode. When reverse biased voltage applied to the zener diode reaches zener voltage, it starts allowing large amount of electric current. At this point, a small increase in reverse voltage will rapidly increases the electric current.

What is the diode function?

A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.

What is the meaning of photosensitive diode?

Answer Wiki. A photo sensitive diode functions just opposite of the LED. In it, current flows on falling of light, when there is no light on the photo sensitive diode then there is no flow current through it.

How are photodiodes similar to regular semiconductor diodes?

Photodiodes are similar to regular semiconductor diodes except that they may be either exposed (to detect vacuum UV or X-rays) or packaged with a window or optical fiber connection to allow light to reach the sensitive part of the device.

What are the characteristics of a photodiode sensor?

What is a Photodiode? It is a form of light-weight sensor that converts light energy into electrical voltage or current. Photodiode is a type of semi conducting device with PN junction. Between the p (positive) and n (negative) layers, an intrinsic layer is present.

What happens when light falls on a photo diode?

On its reverse voltage capacity this diode works as open circuit. Due to this reverse bias, the depletion layer in the diode larger when light falls on the diode than electron hole pair are produced, as a result increase reverse current starts flowing. This reveres current is known as LIGHT CURRENT. Photo diodes have many functions.
