    NPN transistor still working? Strange ..

    Does anyone knows of a great tutorial that explain the flow of current (+charge) travelling through various components?

    NPN transistor still working? Strange ..

    Does "Breakdown" means disappearance of the depletion layer so that the charge can flow across junction?

    And when does the LED turns OFF ?

    NPN transistor still working? Strange ..

    So then how and why does the LED blink (on and off) ? Whats the reason behind that? What controls the timing?

    NPN transistor still working? Strange ..

    Oh! That was detail. Still trying to grasp. So in a nutshell, once the capacitor is energized, the current (positive charge) then flows towards the emitter and breaks down the e-b junction?

    NPN transistor still working? Strange ..

    Ok .. thanks for great replies. I am able to understand all these a little bit! I first want to clarify only with the flow of the current (conventional current that flows from positive to negative)! So when the positive charge starts from the source and cross the first 1K resistor, then after...

    NPN transistor still working? Strange ..

    Thanks so much for the detailed replies.... Just clarifying with some of the above information : Here, firstly I am trying to understand the flow of the conventional current (which is from positive to negative). So in this circuit, I take it as a positive 12v charge starts from the beginning...

    NPN transistor still working? Strange ..

    In above transistor, my question is that as the positive voltage is applied to its emitter (n) and negative is applied to collector (n) does that means electron can travel from collector to emitter overcoming the depletion layer? How can that be possible without applying any positive voltage on...

    NPN transistor still working? Strange ..

    Hello everyone! I am a newbie hobbyist currently exploring more about electronic components and circuits. I have been exploring more about transistors (both NPN and PNP) and how they work. I came across this following very basic single LED blinker circuit built using single NPN transistor...
