    Understanding Lattice Structure & Bipolar Junction Transistor

    trying to figure out the meaning of lattice struction in semiconductor... and, why a small current in the base circuit of a transistor can control a large current in collector part when "bipolar junction transmission" happened? Thanks for any help! :confused:

    Very low voltage drop transistor

    I'd like to construct a fast-reacting current overload protection device. And rather than use a FET as a short to blow a fuse I'd rather just use a semiconductor in series that I can open on overload. This is similar in operation to some "intelligent circuit breakers" based on a Intra...

    How exactly does a transistor work?

    For an exhibit I am doing, I have a transistor as a direct implication for quantum mechanics. How exactly does a transistor work? I know it only shuttles in so many electrons, but what does quantum mechanics have to do with it? Paden Roder

    Music Formula: Transistor Theory Applied

    Music formula. Check out my transistor 1.) God : Thought : Song Intro, the very first sound. 2.) Food : Word : Song Lyrics, the story if you will. 3.) Neighbour : Deed : Song Chorus describing a concept to a neighbour. Like ants or bees. We eat our fill in the world, then describe the...

    Building Circuit w/ 2N3904 Transistor: Can I Use NPN from Science Kit?

    I want to build this circuit http://www.uoguelph.ca/~antoon/circ/fmt1.htm. It requires transistor 2N3904. Is this any NPN transistor or do I have to get a specific one? I have some transistor but it just labeled NPN (from science kit). Can I used that?

    Calculating Emitter, Base and Collector Currents in an NPN Transistor

    The emitter current in a certian npn transitor is 8 mA. If .8% of the minority carrier injected into the base recombing with the holes, find the base current , collector current and the exact value of alpha i am not sure how to get this started thanks joe

    DNA used to create self-assembling nano transistor

    DNA nano-technology is rapidly coming to a point in which applications for mankind will have enormous implications. It now becomes evident that mankind can manipulate DNA that will eventually change the way we live, our health and the world around us...

    Understanding Transistor Concepts: Confusion with R1, R2, and IB

    http://home.netvigator.com/~cyberforce/img/phy.jpg I have learn transistor just few lessons.. For a) what i learn is that R1 and R2 would share Vin that's mean there is p.d. when current flows via R1, R2 thus, Vin = VR1 + VR2 and i am confused if the current flows via them is the same...
