"Microphone makes resistence, so we set up a voltage devider"<br><br>And with that one sentence you explained what 8 hours of googling could not. Thank you so much.

There are a lot of contradicting and confusing explanations on the internet on how transistors amplify a signal on the internet. Your video is practical and easily the best explanation I've found. Well done!

Good video! I like the fact you explain what happens if various values are too high or too low.<br>I'd prefer if your DSO was displayed horizontally instead of down the side of the screen

As always, very well explained. I like the way you also explain why you choose particular resistor and capacitor values and the effects of changing them.

you should have mentioned, for the beginners, that it is not a good idea passing dc current through a speaker not only for heat dissipation but also to decreased efficiency of superimposed ac signals ans since in the emitter follower shown here it is the speaker that determines the quiescent current of operation it may be quite large depending on its dc resistance.
