you sir, made me understand transistors and how they amplify in 2, ONLY 2 videos, while I have effectively been searching and trying to understand this topic for WEEKS now, THANK YOU SO MUCH, IT ALL MAKES SENSE NOW :). I can now finally get over one of my biggest roadblocks in my circuit projects and start doing bigger things. thank you so so much, and keep rocking my man!
I teach an electronics lab and your videos are the only videos I have found that actually make sense. You're brilliant! Keep up the awesome work! (Also your posters are cool)
Ive watched like a 20 videos explaining how transistor works, and this is the first one where someone actually uses a real transistor instead of a fancy animation
I think its not necessary to call both situations "saturation". If base to collector is forward biased = saturation mode if transistor reached its maximum amplification = max amplification, aka we reached the ceiling
I want to clarify something for you all, this is not amplification, you can not amplify current which is set by the power source, you can only control how much of it you are allowing to flow So its like some adjustable knob, not amplification, because the current is capped by the power source connected to collector, and you are just then adjusting how much of that capped current you want to let trough, so, an adjustable knob.
Switch switches, either on or off, amplifier needs a signal to amplify and in this video there is no signal whatsoever , what he explains in the video is adjustment So a transistor is not just either a switch or an amplifier, but theres a 3rd way, which he explains in the video, an adjustment aka using small current at the base to control current at collector Difference between amplifier and adjuster is , is there a signal or no. imagine connecting microphone to base, you talk into the microphone which outputs your voice as a SMALL signal trough the base, and then boom, this same signal exits out at the collector which is where speakers are connected if its same signal just amplified, thats class A amplifier Microphone has red + and black - wires, and speakers have red + and black -, Connect microphone + to the base, black to the emitter Connect speakers red to collector and black to emitter, notice how they have emitter in common ? Common emitter configuration :)
