diode does not work on zero bias

You can buy diodes all over America. You just have to find one that looks like and acts like the one you need. Check Mouser .com Digital Did you try your local John Deere dealer?

Its a Non Linear Device.Its just an electronic switch which turns on during forward bias and off during reverese bias.That is, it gets shorted with minimum resistance and opened with infinite resistance during forward and reverse biases respectively. More over any linear device has to obey superposition therem and homogenity. A linear device is that whose output is directly propostional to input. In case of diode, output (i.e current) is not directly propostional to it input(i.e voltage across it).From it governing equation I=I' * e^(V/V') ,where I' and V' is constant ,it is absolutly clear.

If a circuit element has a voltage of 14V and a current of 70mA, then the resistance of the circuit element is 200 ohms. This is ohm's law. The resistance or type of the power supply is meaningless.

yes, diode can be used as rectifier diode to convert ac to dc

The read type diode are called impatt diode

A diode is used primarily as a Rectifier

Laser diode

zener resistance of a zener diode is the resistance of the zener diode

but which is the resistance of a diode

Diode for what?

Zener diode is heavily doped pn junction diode.

gunn diode is transfered electron device & PIN diode is semiconductor device

whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.

The Zener diode has the characteristics of a constant voltage source.

no

Its not, a diode is unidirectional.

Light Emitting Diode - LED

Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.

Not sure of your context. A diode is a diode. One artificial distinction might be that an electric diode refers to a diode used in a higher power application with more current where an electronic diode might be found on a circuit board as part of an electronic lower power application.

The unit of a diode is the ampere (A), which measures the flow of electric current through the diode. It indicates the amount of current passing through the diode at a given moment.

characteristics if gunn diode

it is a rectify diode

Another diode with similar specifications.

zener

After isolating the diode from the circuit, the diode shows infinite resistance in one direction and low resistance in the other direction. The diode

Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.

diode:= di+ iode

di means two,and iode means terminal,,,, diode is two terminal device i.e anode and cathode

Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.

The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.

An electronic component composed of two layers of a semiconductor material is a diode.

Diode is a two terminal semicon. Diode is a Switching device

It's a high voltage diode, typically used in microwave ovens.

Light Emitting Diode Light Emitting Diode The acronym LED is short for a light-emitting diode.

A diode is a semiconductor material which has p region and n region. In order to "turn on" and conduct current in the forward direction, a diode requires a certain amount of positive voltage to be applied across it. An ideal diode conducts only when the diode is forward biased, and then the voltage drop across the diode (Vd) is zero. When the ideal diode is reverse biased, no current flows.

The two conditions to operate a diode are:

(a) Current flow is permitted; the diode is forward biased.

(b) Current flow is prohibited; the diode is reversed biased. When the polarity of the battery is such that current is allowed to flow through the diode, the diode is said to be forward-biased.

A Shockley diode is a primitive diode identical to a thyristor with it's gate left disconnected.

A Schottky diode is similar to a normal avalanche diode except that it's forward voltage is quite low, and it's switching speed is very high.

due to high voltage across the diode ie more than piv of the diode or current flows more than maximum allowed range of diode.

the amount of voltage applied to the diode

Schottky Diode

another name for diode is "pn" junction.

Unit of diode? It seems irrelevant query

ttt

replace the diode

No. A diode conducts in one direction but not in the other.

diode is unipolar
