Forward Bias Condition: Diode allows only one way direction, the reason for majority carriers flows to minority carrier. higher to lower that's it.
Reverse Bias Condtion: Reverse direction also flows the current, That is Leakage current. it should be minimun for good diode.
For Practical Example: See field work.

Is superposition theorem applicable for diodes?
No, diodes are not linear elements like resistors are. Current can only flow in one direction in diodes.
What happen to diode in parallel circuit connect into the series?
Diodes only allow the current to travel in one direction, they are often used to prevent current leakage from one point to another, "basically the current can back up and go into other parts of the circuit without the diode. If a Diode is placed in Series with a circuit it will only allow the current to flow in one direction. For instance in Power supplies that convert AC electricity to DC they use a special diode Called a bridge Rectifier, Basically it used 4 Diodes in series to smooth out and condition the power so that when it comes out it is only Positive and Negative Diodes are also Half wave, meaning that only half of an AC cycle will come out the result is an Oscillating DC. So when a Diode is in Parallel with a component it is either Bypassing that component in one direction or it is disallowing the current to flow Backward on the component..
What device will allow ac current to flow one way and not the other?
A diode may be built for high levels of current and voltage. There are diodes for low current and voltages too. They allow the ac current to flow one way and block its return. The first diode that was built a long time ago by Sylvania Co. USA, was named IN34, and could stand only very low current. Other name for that device is a rectifier. Ancient valve tubes for radios contained a diode inside which main function was to provide cc to feed the filament of a valve. This filament had the function of emitting electrons towards the plate of the valve. JW70
What are the problems of series connected diodes and what are the possible sulotions?
A: The question remains why would anybody connect diodes in series to begin with only one is necessary. So the solution is use one
What happens if one of the four diodes in s bridge rectifier is reverse?
four diodes
Why diode is called mechanical valve?
A valve allows flow in only one direction. Diodes allow electrical current to flow in one direction only.
What is the uses of semi conductors diodes?
allow current to flow in one direction
How do alternator diodes work?
Diodes allow current to flow in one direction only thus changing the alternating current produced inside the "alternator", to direct current which is required by your car's electrical system. Think of them as check valves for liquids. Denis

Does alternator diodes prevent battery discharging?
A diode is a one-way valve for electricity. Since an alternator produces alternating current, the diodes allow electrons to flow in only one direction. That's how it converts AC current into direct (DC) current. There are usually three diodes in an alternator. It's called a diode bridge and is also known as a "rectifier". Revised answer. Yes it's called a diode trio. But there are actually a total of six diodes in a complete rectifier bridge. There are usually 3 stator windings. Each winding has two diodes. One diode allow positive to the battery and the other diode prevents positive from flowing to ground.
What is true about diodes?
Lots of things are true about diodes. There are different types of diodes; their general characteristic is that they have two electrodes (electrical contacts). They conduct current in one direction only.
What is a true statement about diodes?
Diodes conduct current in one direction A+

What is used to limit and control the flow of electricity?
hmm in a circuit diodes are used to allow current in only one direction,resistors are put to prevent too much current to pass, hmm there are also fuses which prevents current's overflow!there are various things to limit and control current!
What are the classifications of diodes?
a diode is a device that alows current to flow in one direction you have power diodes which are used in rectification processes and high current operations but the two main families of diodes are solid state diodes or valve operated diodes.
What does it mean to say a diode has a forward bias?
Diodes allow current to flow in only one direction, and if the diode is put a certain way around in the circuit such that it DOES allow current to flow, then it is forward biassed. If the diode is put in the circuit so that it doesn't allow the current to flow, then it is reverse biassed.It is just a term used to describe the orientation of the diode relative to the (conventional) flow of current through the circuit.
How transistor acts as bidirectional?
its because it only allows current to passy through one direction. They are like diodes
