Transistor

Transistor
It is three terminal semiconductor devices, it is equivalent to triode, when grid is added to diode it becomes triode, it is used in amplifiers, oscillator, switch etc. transistor was invented by John Bardeen, William Shockley and Walter Brattain, all of them got noble prize, the name transistor was suggested by John Pierce because it is synonym with Resistor, conductor etc. BASIC TYPE OF TRANSISTOR  Bipolar junction ...

Diode

Diode
DIODE When p-type material and n-type material join together it makes a diode. TYPES OF DIODE There are three main types of diode Silicon Diode Light emitting diode (LED) Photo diode SILICON DIODE Silicon diode is a common type of diode which is made up of silicon and it is basically used to design circuit. It produce energy when battery connects to it, it produce energy in form of heat. PHOTO DIODE Light emitting diode ... Full article

PN Junction

PN Junction
PN junction is a combination of P-type and N-type regions. P-Type P-type is a region which contains a majority of holes or vacancy in it and it also contain a less amount of electrons. N-Type N-type is a region which contains a majority of electrons in it and it also contains a less amount of ... Full article

Doping

Doping
Adding pentavalent or trivalent elements to pure semiconductor is called doping Or we can say that adding impurities to pure semiconductor is called doping.Doping converts intrinsic semiconductor to extrinsic semiconductor. Why we use doping? In electronics sometime such devices need extrinsic semiconductor that’s why doping is done and to break covalent bond of semiconductor we often use process of doping. ...

Covalent Bonds,Electrons and Doping

Covalent Bonds,Electrons and Doping
COVALENT BONDS A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, or between atoms and other covalent bonds. In short, attraction-to-repulsion stability that forms between atoms when they share electrons is known as covalent bonding. In this figure of ... Full article

Electronics
ELECTRONICS It is the study based on the flow of electrons to design circuits, devices and systems using resisters, capacitors, semiconductors, vacuum tubes etc ELECTRICITY It is the energy given by the:     Batteries     Generators     Solar cells etc.   Unit of electricity is kilowatt/hour. ORIGIN Electrons, electricity, electronics all begin with “ELECTR---” originate from Greek word “ELECTOR” meaning “Beaming Sun” also elector is used for “AMBER” (Arabic: a jewel quality ...
