CAN WE PRODUCE CLEAN ENERGY ?

World is full of advancement today from previous era , we have astounding facilities good lifestyle better food and more but did you ever feel amazed how all of this possible today which was impossible before , all of this happens because of our developed technology of converting energy from one form to another with increased efficiency . but we are again at the bank of river of question's  , question which is seducing me from past several months and its attempt to draw my attention is legal too because of our current condition  a problem of ENVIRONMENTAL POLLUTION who is grown up baby now of our human race and its age is from industrial revolution to today's date . if i play little maneuver to our problem of environmental pollution to a QUESTION as              " is there any way to get immense treasure of clean energy ? " like we usually do in mathematics , and if yes than how , here the clean energy source ...

WHAT IS LIGHT EMMITING DIODE ?

LED is a very commonly used device nowadays we use it in various application because of its small size and,cheap prize its very popular among peoples . we use it even in special television set for screen as LED pixels which is useful for clarity for distance audience . basically it is a diode which is set to be in forward condition .   Full form of LED is LIGHT EMITTING DIODE . As evident from name it is diode who produce photon when voltage is given to it . this type of diode is not made by generally used semiconductor's like silicon and germanium it manufactured by arsenic phosphorus and gallium . various types of color can can be produced by changing quantities of material it made up of .  WORKING - Basically it is like a normal diode just difference with it produces light when a forward voltage applied to it . as we know  electron needs energy to jump from lower orbit to higher orbit ,  the working of LED is typically reverse of this process electr...

WHAT IS THE SECOND LAW OF THERMODYNAMICS ?

First law of thermodynamics only taught us about the temporal nature of world by which we can only transfer energy or thermodynamic coordinates in each other at the rate of mechanical equivalent of heat also known as joule's equivalent which is defined as - " we have to do 4.18 J of work to produce 1 calorie of heat " But second law of thermodynamics give us proper understanding at which term and condition are employed by nature for transformation of thermodynamic coordinate's into primary interest for understanding of how transformation will occur between heat and work . i want to emphasize one more point about this law, isn't a absolute law about which we will discuss in microscopic level of second law . considerably there are four scientist's worked on second law , Rudolf Clausius , lord kelvin, max Planck & Ludwig Boltzmann , first three of them worked on...
