"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.
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.
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.
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?
I havn't watched this video yet, but oh my god man i know you'll help me out with this cause my professor explains like we understand xD, thank u for being of help
There are 2 ways to bias the transistor...one way is to set Vce to half the supply voltage. The other way is determine Vce sat and Ic max then look at the middle Q point operating on the graph of the transistor characteristic. From that find the nominal hfe.
Well, the assessment that when the transistor is either in saturation or cut off is “not very helpful” is wrong because actually that’s the main use of a transistor: as 0 - 1 switch. That’s the basics of digital electronics!
Can anyone explain how a DC current (whether in a tube or transistor circuit) can mimic AC? By definition, direct current GOES IN ONE DIRECTION. The "downward slope" of an AC sine wave makes sense to me. The upward part doesn't, as it requires the current to reverse direction. PLEASE don't quote "bias" or the original sine wave wave or the mathematics of an arbitrary null point. I understand the math very well. I don't understand what should end up as just a half wave rectification, becoming a (genuinely) alternating current, i.e., changing from positive to negative. I also know that circuits work, according to the maths. So in not questioning the practicality. It's just so damn frustrating how people are not questioning this fundamental physical anomaly.

Can't count how many times this channel has helped me out
Bro you're a life saver love from Indian Institute of information technology Nagpur
This is the clearest explanation of DC load line I've heard!!! Great content!!! THANK YOU!
I’d be happy if my semiconductors professor was a tenth as good as you at explaining this stuff. Excellent video!
I'm taking the same COURSE AND IT HURTS OMGGGG
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.
post more content on your channel! We can never have a shortage of well-explained physics concepts, especially for EE students like me!
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.
Very nice explained, I have Q-Point in my pocket now!
This was a great lecture. Showing the direct load line graph helped me to crystalize and clarify several points that I was hazy about.
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!
I have presentation about this topic and i finally understand and got present very well thankyouu man you saved me
Good problem solving sessions ,a kind request to keep more of these ,these are lifesavers! Thanks man..
Excellent video - a clear explanation on BJT biasing circuits.
Very clearly presented, easy to follow. Thanks!!
Very well done - to the point, well described and easy to follow!
I really hope you can make a series of tutorials about the AC circuit . thank you so much for helpful content
Priceless video!! Thanks!
This is quite helpful. Thank you very much!
This is a video on how to plot dc loadline: ua-cam.com/video/Rqpiz6_3OUw/v-deo.html
awesome content
So helpful, man. Thank you very much for this video! Keep up the good work.
lovely stuff
great to learn or relearn video.... nice to re-see this q-point info before making an arduino circuit... thanks a lot...:)
Did not have much knowledge about transistor, but this video enlightens me much. Great job!
Thank you, you saved my life
great video , i am searching for an long time ,thx
What! Incredibly excellent!

i wish if my teacher is as good as you
i love how he teaches everything although his name is organic chemistry
Your a life saver
When Vce comes negative...how will be the dc line...or the negative sign doesn't affect?
Thanks so much! My electronics course didn't teach about load lines when we were learning BJTs.
Also does anyone know what "Base Bias" means?
From india 👍❤️🇮🇳
Thank you bro
Can we use the information on the datasheet to design an amplifier?
Thanks for the video
Please i wish to know the software you used in writting in your video
Thank you
brilliant
How about common colector for increase current, is the q point and dc load still be calculated?
i hella love you man
does q stand for quiescent? so the quiescent voltage is the voltage at the q point?
would it make difference if there was a RE resistor and R2 resistor under RB ?
Thank You !!
Bro is "The Everything Tutor"
Helpful
Thanks 🙏👍💯😊
ty OCT!
Is Vbe and vb the same?
how could we know that the IC value we choose is in the appropriate region ??

DO you have a powerpoint for this one?
Can you do this video with PNP transistor
Hello. are your playlist organized? like the first video is lesson 1 and the next video is lesson 2 like that
What software do you use to draw all that ?
11:45 is it always true - "potential between C and E is = half of Vcc" or in this particular example?
Thats for a centered q point
TNAK YOU
perfect

Can we take beta value as random like 100,150,200..🤔
No it is given in the question
@@thelegend2543 but what if it's not given in the question?
Do ACLL please

organic chemistry hmm interesting
I don’t know but m more confuse 😢
