Diode in simple terms is a "One Way" Device, i,e it allows current to flow thru in one direction only.
Diodes are the most indispensable part in the electronic/electric World.

Which mode is use in digital multimeter for testing of diode?
A: For a digital meter to test a diode it must have a scale for resistance for it to work, If not a 1.25 v cell with series limiting resistor will work. If you measure across the diode the reading should be .7 volts reverse the cell polarity then the diode voltage should be 1.25 v .7v is forward voltage 1.25 is reverse voltage.
What is the solid state diode?
A solid-state diode is a diode where the electrons flow through only solid materials. Nearly all diodes in common use are solid-state.
How does clipping circuits work in lab?
A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity. In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.
How do you identify the polarity of a diode when the tester is on diode scale?
To my own understanding, you will use multi-meter to test for the polarity
What is the negative leg of an LED called?
The side of any diode that must be negative in order for the diode to conduct is the "cathode".
Diode will work on zero bias or not?
diode does not work on zero bias
Practical diode model define and explained?
a way of diode modelling in which diode just work as an energy source in the circuit
Does a diode works when the ignition key is off?
No a diode will not work when the ignition key is off.
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
How do LEDs work?
L.E.D. Stands for Light Emitting Diode so it is a Diode that makes light...
How transistor work as a diode?
A: Actually a transistor have two diode with the base mas a common terminal. the characteristics of these tow diodes however are not the same as a common diode
How diode work as semiconductor?
Diode is made of P and N type semiconductors having PN junction. The question is meanigless.
Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
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.
Can diode work as switch?
yes diode can be used as a switch as it conducts current in only one direction.it is a open switch when it reverse biased.and as aclosed switch when it is forward biased.but we consider diode as ideal .
How does a p-n junction diode work as a switch?
diode conducts in forward bias.so it is on switch. in reveres bias it will not conduct.so it is off switch
How does a semiconductor diode work?
A bit too complicated to describe here, see the following for lots of detail. http://en.wikipedia.org/wiki/Diode
