"The Organic Chemistry Tutor"... Kind of a trademark name for a chemist handling physics so exceptionally! Thanks a lot for all these years... Please never stop.

[connivingkhajiit]

Can't count how many times this channel has helped me out

[educationwitheleanor]

Thank you for this video. I have used a lot of your videos in my physics classes. It has inspired me to create my own channel for my physics students. They are loving it. Please don't stop.

This is the clearest explanation of DC load line I've heard!!! Great content!!! THANK YOU!

[Cobras]

I’d be happy if my semiconductors professor was a tenth as good as you at explaining this stuff. Excellent video!

[shvideo]

Great tutorial in physics by a chemist! Who knew that you can top them all?! Thank you for the detailed explanation. Your great effort is much appreciated on this critically important and versatile component.

I have watched so many videos on q point but this one i can perfectly understand.

[successthruknowledge]

This was a great lecture. Showing the direct load line graph helped me to crystalize and clarify several points that I was hazy about.

[samogo]

Very nice explained, I have Q-Point in my pocket now!

[HBs-mbrr]

Good problem solving sessions, a kind request to keep more of these, these are lifesavers! Thanks man..

[tomherd]

Very clearly presented, easy to follow. Thanks!!

[RAJIBLOCHANDAS]

Excellent video - a clear explanation on BJT biasing circuits.

[datchentai]

This is quite helpful. Thank you very much!

[IvanGeorgiev]

So helpful, man. Thank you very much for this video! Keep up the good work.

[iroksaggio]

Very well done - to the point, well described and easy to follow!

[dirafneer]

I have presentation about this topic and i finally understand and got present very well thankyouu man you saved me

[ucnongvan]

I really hope you can make a series of tutorials about the AC circuit . thank you so much for helpful content

[PunmasterSTP]

Perhaps I'm biased after watching some of your other content, but I think this video was loaded with with information that was truly on point!

[qzorn]

great to learn or relearn video.... nice to re-see this q-point info before making an arduino circuit... thanks a lot...:)

Beautifully explained. I find myself rewatching and reannotating your videos, lol. Taking more notes in case I missed anything.

One question I have is, how is this applied to amplifiers? Can I just use this method and plug my guitar or a line-level signal into the base and expect an optimal amp or is there way more to it?
