The simplest way is the Ideal Model representation of a diode.

Forward: V=0(short circuit),r'd=0,I=use Ohm's law.

Reverse: V=Vbias(Open Circuit),I=0,r'R=0.

Ideal model means it is acting as a switch.

Can a diode be used as rectifier diode?

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


How real diode is different from ideal diode?

It depends how "ideal" your ideal diode is. The first approximation of an ideal diode is that it's a device that allows current to flow one way, and not the other way, while doing this with no losses. The second approximation of a diode implies the inherent 0.7V drop across the device, as well as one way current flow, but with no loss resistance. The third approximation of an ideal diode is a device which allows current to only flow one way through it, with a 0.7V loss across is, as well as a small internal resistance of a few ohms. These all vary from a real diode because these are all linear, in every sense. You can neither calculate the voltage nor the current across/through a diode. Instead, you must use the diode's characteristic curve (given on datasheet), and linearize it. You can get any amount of current to flow through the diode the CORRECT direction, by changing the voltage used. A number of microamps will take perhaps, a third of a Volt.

How do you check if a diode is serviceable?

use a vomm set to infinite resistance if you have reistance one way and not the other way. diode is good (must be isolated from circuit) if no resistance both directions diode D.O.A.


When does the diode not allowed to flow the current?

A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.


How does a diode work on an engine shutoff solenoid?

A diode is a one way check valve basically. it will let current pass one way but not the other.


Is it possible to check diode and zener diode in laboratory?

yes, of course it is. one way is using a curve tracer.


How can you visualize infinity?

I fun way to visualize infinity is to stand directly in between two parallel mirrors. A Mobius strip can also help visualize infinity.


What is the characteristic of a diode when electrical current passes through it?

A "diode" is any of several devices; the only thing they have in common is that they have two electrical connections - hence the name. These devices have different functions. The simplest semiconductor diode, and one of the most common, is probably the rectifier diode. It lets current pass in one direction, but not in the other direction.


What is the functions of a diode?

A diode is basically any of a great variety of circuit element that has two electrical connections. They serve many different functions. The simplest type, the rectifier diode, only lets current through in one direction - but there are other specialized diodes, like the LED (light-emitting diode), to name but one. A diode can also be used as a clamp, and as a detector (mixer) in an a.m. receiver.
