    Voltage divider bias

    In Voltage divider bias , we are not drawing any electrons from the base. Then how can the electron current pass through the base and go to the collector and reach the positive terminal. Only if You draw electrons from the base by maintaining the base at positive potential, then only the...

    NPN PNP OP-AMP Water analogies

    i have posted the pnp npn and op-amp water analogies. Could someone explain me pnp and op-amp water analogies.I have understood the npn water analogies but i have many doubts in it which i will ask after i understand pnp and op-amp water analogies. eventhough the explanation is given in the...

    Faithful and unfaithful amplification

    I have somehow managed to learn unfaithful amplification from this book. http://books.google.co.in/books?id=CKTS6BzQqm8C&pg=PA226&dq=transistor+amplifier&lr=&ei=uBUtS_L2N6K-lASzxqmtAw&cd=6#v=onepage&q=transistor%20amplifier&f=false [Broken] The book has very beautifully explained the...

    Transistor AMPLifier HelP

    Transistor AMPLifier HelP !!!! could some1 explain it entire circuit in terms of electron movement i.e how the voltage drops in each component in terms of electron flow 1)i cant understand the voltage divider bias i find it extremely difficult plz explain it interms of electron movement in...

    Voltage drop in diode

    the depletion region is resposible for voltage drop all that is fine but in forward bias there is no depletion region hence there can be no voltage drop but it is mentioned in my book that the voltage will drop by .7 volt how come this can happen also i have many doubts in transistor...

    ZENER BREAKDOWN has caused me a breakdown

    could any1 plz explain avalance effect i can understand that the electrons minority carriers are accelerated by high voltage and collide with valence electrons break free them and what happens after that do they all go back to the positive terminal plz explain after the production of avalanche...

    Transistor AMPLifier HelP

    Transistor AMPLifier HelP !!!! i will start from the first plz clarify my doubts i will post my other doubts as and when i get replies and answers my first doubt is what is meaning of Vbe base emitter voltage and also Vce collector emitter voltage what is the actual meaning of these...

    AC with INDUCTOR IMP DOUBT

    What i know the most fundamental thing is that the emf supplies energy to the charges and these charges have to reach the other end(say for electrons to reach the + end). IN order to do that somehow or the other they have to drop their voltage or energy for this to happen . AC with inductor...

    Transistor cant understand even a bit

    i cant understand the transistor completely i can understand how it works but this stupid conventional current is confusing me completely plz can any one give a lengthy explanation on working of transistor CE CB CC types. i dont understand all these types of transistor i.e how current...

    Antibonding MO do they exist in reality?

    do antibonding molecular orbital exist in reality or is it an empty space in which an electron can move about freely and not involving itself in bonding. if they exist then how can the 2 atomic orbitals interfere both constructively as well as destructively simultaineously to give both...

    Fermi level simple explanation

    can any1 explain what fermi level is simple explanation also how are minority charge carriers formed and i cant understand the energy band diagram of pn junction that how both the fermi levels become equal WHAT IS MEANT BY THAT FERMI LEVEL i read in hyperphysics but i cant understand it .CAN...

    RLC Circuit qualitative explanation! any1?

    can some one explain me the qualitative aspects of RLC circuit i am satisfied with the vector diagrams i want the physical meaning behind say for instance in ac with inductor when current varies induced electric field is set up which opposes the current so there is a voltage drop similarly...

    Mass expansion

    relativity states that as v approaces c mass increases but my question is that if we are going fast and suddenly mass increases then simultaineously we must slow down and thus we will be back to original state by this hypothesis i believe that mass expansion is only for minute seconds AM i...
