Diode Diode       D iode is a electronic component which use every electronic circuits. How to work a Diode                         Here two types of semiconductor add to make a diode the two semiconductor are P-type  Material  and N-type Material.               In p-type material have Hole. And P-type material have electrons. When a N-type material donates a electron to P-type material and N-type became a positive ion. N-type material also called Donate Material.

Insulators, Conductors and Semiconductors Insulator I nsulators have no conductivity because of there is no conductivity electrons. Because of there energy gap between valance band and conduction band (5eV)                                                          Conductors Conductors is high conductivity material. because of there no energy gap between valance band and conduction band. Semiconductors In semiconductors small energy gap between valance band and conduction band. The conductivity of semiconductors lies between Conductors and Insulators. When the temperature is low, semiconductors behaves like a insulator, When increase the temperature more and more semiconductors behaves...

Types of semiconductors 1)   Intrinsic(pure): A semiconductor which is extremely pure is called intrinsic semiconductor. In intrinsic semiconductor two most important semiconductors are Germanium and Silicon 2)   Extrinsic(impurity): Certain amount of desired impurity is added. The process of adding impurity to pure semiconductor is called Doping Two type of impurity 1)   P-Type semiconductor 2)   N-Type semiconductor P-Type semiconductor When a small amount of trivalent impurity is added to the pure semiconductor P-Type is formed N-Type semiconductor When a small amount of Pentavalent impurity added to the Pure semiconductor N-Type formed

PN JUNCTION: Formation :- The N and P-type semiconductors are basic building blocks for semiconductor devices. Joining of N-materials and P- materials type semiconductor forms a PN junction which is importance in electronic systems.         PN Junction formed by doping of N-type impurity and P-type impurity side by side in a single piece of semiconductor. And it’s called PN Junction diode Inner of diode

CHEMICAL REACTIONS            Chemical Reaction: The things which occurs new substances                                        form with new products.                       There are four types of chemical Reactions:                                   1)Combination Reaction                                   2)Decomposition Reaction                                   3)Displacement Reactions                                   4)Double Displacement Rea...

ELECTRICITY 1) Charge is a fundamental particle in an account in an atom.It may be positive or negative. 2) Like charges repel each other. 3) Unlike charges attract each other.       Coulomb(C ) :S.I.unit of charge      1 Coulomb = Charge present an approx.6*10 to the power of 18 electrons 4) Charge on 1 electron = Negative charge of 1.6*10 per C                                                      Q = ne Where     Q = Charge(total)                 n = No. of electrons                 e = Charge on one electron Current(I):   the rate of flow of charge is called current.                               ...
