    This would have been invaluable when I did my EEE degree many years ago. I use to draw the charge carries instead.

    That's really cool. I am again planning to focus more on maths n physics...Hope it helps along..thanks

    Ohhh. I have no real knowledge of electricity or electronics, but I know transistors are very fundamental so if you squint a bit, you might say this is what we set in motion when we program, or even just use a computer! Or at least some of it. Not knowing enough to benefit from it I learned nothing, and don't regret a second of that.

    Thanks, I have an EE education, but I didn't really understood what charges were doing in a BJT. I can use them and apply the formulas, but I never really "grokked" them. This makes it clearer.

    I wonder how difficult it would be to convert these to 3D

    This is really cool. It would have made understanding these so much easier when I was learning.

    One minor suggestion - show the voltages in all the animations.

    This is one of the coolest animation/diagrams I've ever seen, I wish they had them when I did this at uni. It sure beats whiteboards with scribbles and arrows all over it...

    it kind of looks unrealistic that there's so little flow, but I guess that makes sense for micro-sized transistors, larger ones that can handle several amps at high voltage should behave differently and would be a rather interesting comparison.
