    Common collector configuraton

    So if beta = 300, thrice the current will exist (Emitter current), but how? I only knew few equations that's why I went through all this steps to connect beta and Ie. but from your reply "You'r lost at sea" I guess I'm wrong. So please clarify how it gets changed depending on gain?? Is...

    Common collector configuraton

    I know, I'll be hard to teach idiots like me but I still have few more doubts. And hope you have patients for that. :) This what I understood so far, When a base voltage is applied base current flows and this is multiplied by transistor gain to produce a higher current, this current causes a...

    Common collector configuraton

    In the main post , I said I meant emitter is not connected to GND. Yes, for the transistor to trun on Vbe = 0.6. In common emitter mode, emitter is directly connected to ground, so by by giving a base valtage of 06-0.7V , one can turn on the transistor(Vbe= 0.6-0.7), but in common collector...

    Common collector configuraton

    Hi, Can anyone help me understand how common collectro configuration works in a an NPN transistor. In common emitter configuration, Emitter is connected to ground and load is connected to Collector. When a sufficient base voltage is applied, E-B will become forward bias and...

    3d Printer extruder issues and some other doubts

    I've using both boards for around 6 months. I never had the problem. Both etruders turn on only when command is give to turn them on , otherwise it was OFF with or without USB connection. Second extruder issue happened recenly. SO I think it's an issue with control board.

    3d Printer extruder issues and some other doubts

    Do you have any idea why is the extruder turning ON when USB is disconnected? Could this be the regulator issue??

    3d Printer extruder issues and some other doubts

    If there was any logic inversion, shouldn't it have shown in the schematics?? Also what do you think about automatic turn On of extruder?

    3d Printer extruder issues and some other doubts

    Hi, First of all I don't have much experience in electronics (yes I'm anelectrical and electronics engineering graduate(fresher) but I'm more interested in power system) and I like to do hobby electronic projects with my basic knowledge in electronics. I'm having some problems with my 3d...
