How many type of diode?
There are many types of diodes that are used for different functions in electronics. The most common types include the laser diodes and the light emitting diodes (LED).
What is the history of germanium diode?
Germanium point contact diodes were first created and used during World War 2 as detectors in microwave RADAR systems, as the vacuum tubes available at that time did not operate at microwave frequencies. Shortly after World War 2 germanium junction diodes were created.
What are the applicaton of diodes?
Diodes can be used in the following domains:In rectifier circuitsin display circuitsas switches
How do diodes affect electronics today?
Diodes are used in almost every electronic device, if that's what you mean.
When diode is used as an amplifier it is operated in what?
Diodes are not amplifiers.

What are the Applications of Diodes?
These diodes are used in a variety of applications from low power radar systems to alarms. A major drawback of using IMPATT diodes is the high level of phase noise they generate. This results from the statistical nature of the avalanche process. Nevertheless these diodes make excellent microwave generators for many applications. A main advantage is their high power capability. They operate at frequencies between about 3 and 100 GHz or more. http://artizle.blogspot.com
What kind of diode used in an amplifier?
Lots of kinds of diodes are used in amplifiers. In the power supply section, diodes may be used in groups of two or four, as rectifiers to convert AC (from the mains supply, via a transformer) into DC for the amplifier. These diodes are usually rated at several hundred volts, and several amps. They are classified as rectifier diodes. A typical example is 1N5404. In the amplifier circuitry, diodes may be used to provide a known (approximately) voltage drop where required by the design of the circuit. They can also be used for temperature feedback, although for direct temperature compensation a transistor is more common. These diodes are generally small-signal types like 1N4148. In logic switching, diodes are often used for simple OR-type functions. Look on Wikipedia for "diode OR". These are small-signal types. If the amplifier has a switching power supply, or is a Class D amplifier, high speed switching diodes are used extensively. They are used for rectification (though they must be high-speed devices because of the high switching frequency), suppression and clamping in the Class D output stage (ditto), and miscellaneous functions in the control circuitry. These are high-speed, high-current diodes.
What current types are diodes used in?
Direct Current or DC

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.
Frequency and cumulative frequency are two types of what?
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
Diodes are commonly used for?
diodes are commonly used for rectification
Are diodes rectifiers?
No. Diodes are diodes. One diode can be USED as a half-wave rectifier. Four diodes can be used to build a bridge rectifier.
What type of diodes are used in bridge rectifier?
Mainly diodes that handle a fair amount of power. When diodes are constructed in a "bridge", it usually means someone is trying to rectify AC to DC voltage in what is considered a "full wave". Both sides of the sine wave + and - are utilized to change the AC current into DC. Typically power diodes are used in this fashion. Crystal diodes or other types will not work in a bridge circuit as they cannot handle the amperage or wattage that typically is wanted. Power diodes are usually ones that handle 1 amp or more of current. Some power diodes can handle 60 amps or more if properly constructed in a heat sink dependent upon their ratings.
Which rectifier is not directly operated from mains?
Because , the high voltage can destroy the diodes used in the rectifier .
