    A Good and simple explanation of how a switching Transistor works. Thank you

    What about the Saturation state response, and the minimum required voltage/current on the base?

    Why do you have a separate power source as well as power from the led circuit to the base of the transistor?

    What software do you use to simulate your circuits? I love the way you use it! It makes it easy to visualize what is happening at the atomic level.

    I'd compliment you on your video but, of course, I realize you're just a robot.

    Hello, Why both voltage source are not summed to each other resulting a source of 15,5 volts?

    Loving your channel man. These videos are excellent. Also, you have a really good voice. Extremely clear and articulate

    I can get current to flow through my Base-Collector and Base-Emitter to light an led.
    So what is the point in using transistors if I can connect the led directly?

    What is the point in having three pins at all if I might as well just use the Base-Emitter? So the collector is useless.
    Does the transistor need a seperate power source to function properly?

    Been trying to learn electronics for some time now but I give up every time because transistors simply won't work the way they are said to work.

    Either my transistors I've been using are broken, or my brain is broken.
    I would like some help to clarify.

    so why in this video did you flip the – and + volt upside down where all of the previous videos are opposite? a bit confusing.

    someone below suggested your circuits were drawn using 'every circuit' but Apple store has nothing by that name, is the name correct?

    2:50 I’ve watched so many videos and never understood transistors, and these 30 seconds explained it to me better than anyone else ever could (I’ve worded this comment funny, haven’t I?)

    In previous videos you showed the flow of electrons going from negative to positive charge yet in this vid you show the flow from positive to negative – so I'm confused.
    which is it?

    Thanks for the video but I think I'm getting confused. In one of your previous videos on DC circuit about how electrons flow, you stated it flows from from the negative through the load to the positive. But going a bit off the transistor topic on this video, you state current flowing from the positive through the load to the negative. Can you please shed some light on the directional flow of current and electrons in a DC circuit please?

    What stops the high voltage from feeding into the smaller voltage power supply if these lines are connected like they are? I've seen this done with relays, using coil to magnetically flip a switch… so they are not electrically connected. How is this similar?

    Why use a transistor when the same thing happens without one. That's what i can't comprehend. Can anyone help me ?

    The first diagram shows current flowing out of the transistor collector back to the 3.3v power supply and out of the emitter to the 3v power supply but in the video it says that the current goes from the led through the transistor back to the 3v power supply. I thought when the transistor is turned on that current only goes one way through it? The way it’s drawn out in the second diagram makes sense to me but the first one has me confused…can anyone help me understand a little more please?

    Is this explanation works for both npn and pnp transistor?
    please let me know.
    Im so confused.

    So, to use transistor fast, we need to program microcontroller to do that? or is there any other applications that can turn that switch so many times in a second.
