You are a great teacher. You explain things concisely, clearly and in the right order to make it easy to understand.
Really cleared up the mystery surrounding zener diodes for me. Really appreciate the vid!
Current flows from negative post of battery to positive post. In a Forward biased diode, current flows against the arrow. You're backward in your theory.
@@lawrencebaxter9448 this uses conventional flow, + to -
Thanks for helping us to rectify our misunderstandings! All of your videos are wonderful, and thank you so much for making and sharing all of them.
Thanks so much for making this video! I was unclear what would happen when 2 diodes are placed back to back and your explanation made total sense. All the best to you and take care!
hello, i am a student in avionics systems and have found it hard to find any good explanation but must tell you that this is by far a very good explanation, thank you very much for the video, i will certainly look for more on you're channel.
O_O i am a student of class 12th in india ( amazing that 12th study is used in engineering )
thats why everyone studies in school till 12th grade. we even use addition and other basic mathematical operations in higher studies that we learnt in 1st grade@@sambhavkumar3865
I've been confused with this topic for weeks...read the whole chapter too, still left me confused. Professor himself was confused what he was doing. Your 11 minute video cleared that all up. Thank you!
I was studying electronic 20 years ago and I didn't like as I didn't understand. Now I try to truly understand by searching in this TH-cam, and I now understand it very easy.
My Electronics course uses the book "Microelectronic Circuits" by Sedra & Smith.
I am not really a fan of that book, since I find it dry and long-winded.
I tend to prefer "Fundamentals Of Microelectronics" by Razavi - it's not QUITE the same content, but it's very similar, and includes typical topics such as diodes, transistors, small-signal models, rectifier circuits, and so on.
It doesn't include zener diodes though, but it has a teaching style that I definitely prefer over Sedra & Smith.
And also, Razavi himself has tons of videos on several Electronics courses, and has a pedagogical style much like The Organic Chemistry Tutor.
Test in 4 hours and this is a savior. Thank you!
Hope you're test went well..
@@TheMen002 are you sure xD xD
How’d the test go!
Your methods of explanations in basically all your videos have carried me in my courses of electrical / electronics theory. Thank you!
such a calming, informative and easy to understand video about Zener diodes. Step by Step guiding us with a relief
If you are NOT in some school teaching, someone is not doing their job correctly.
For the first time in my life realized about the zener diode🙏🙏🙏❤️❤️❤️
Same here 😀
Perfect !!!
No other video can explain zener in such a simple n perfect manner
Simplicity rocks 🎉
I’ve already noticed that people who have this kind of voice, the way the explain stuff is outstanding. I think about Brad Traversy.
i have an exam in 2 days, this cleared up alot of things, thank you
How did your exam go?
@@bojangorgioski6353 Yeah that makes sense, but I’m always curious to know. I started replying to “Thanks, I have an exam coming up!”-type comments a while ago, and it’s led to some cool conversations…
1 hour for me
thanks mate this was a great video. nice to see it in the basic series circuit and then put into AC like that. i think the order you showed things is just the right way to do it. this is going into my permanent stash of educational resources
Thanks for the videos. Very easy to understand. Just started getting into electrics and this is very helpful.
youre content is life saving, THANK YOU!
Very clear explanation of zener diodes. Thank you.
Dear Sir, you are a genious bcause despite being a organic chemistry tutor you know everything about Electronics which is totally different discipline
Its the best chanel on youtube for clearing concepts . Hats off😍😍
A very good lesson, even for someone with a weak English like me...
Very comprehensive and easy to understand.
Crazy awesome tutorials. Good job man ✌
A great introduction to Zener diodes. Thanks a lot!
Thank you very much. That last circuit explanation helped me a lot!
So, in summary, can we say that a Zener diode acts as a voltage regulator?
Yes
I wish I found you 2 years ago so that this day would be different I was not afraid of this day so that I was not scared of what is going to happen next . I wish I found you before and thank you for what you have taught me still in 6 months
yoo you literally got every topic i wanted to learn. thanks
This is cool! Thanks for the video!
I'm sure my teacher didn't teach me but you teach me . you are good teacher . God bless you.
Ive learned more than one or two thank u so very much
Very good explanations,not very often seen on You tube..Thanks.
great explanation as usual, thank you
My favorite tutor
This is an excellent tutorial.
Thanks for your video it helps my channel grow.
great video. you are a good teacher.
Your videos are very useful. Thanks
Very clear! Thank you
You are brilliant! Thank you!
Great tutorial video!
Beautiful tutorial!
Great explanation. Thanks a lot !
crystal clear! thanks!!
Thanks a lot! That was pretty easy to learn this 👍🏻
This video is made for dummies like me. Thank you n happy Thanksgiving ☺️
Awwww..... don't call yourself that🥺🥺
Excellent tutorial.
Thank you
I wish you were my professor. Your videos help me a lot.
Fantastic explain .. my first teacher in IT engineering collage❤
Very good presentation!
Amazing video!!!! Absolutely fantastic!
Thank you 😊 excellent and simple teaching 👏
Yes, I have learned a thing or two from your video!
I wish you were my lecturer 47 years ago!
Really appreciate......the examples are very useful and valuable.
Amazing explanation!!!
Althouh Zener Diodes are a bit old-school, they do have some modern applications. Back in the 80's, I worked on the first Transatlantic Fiber Optic Cable (TAT-8). It had repeaters every 25 Kilometers or so. The power for all the repeaters was several thousand Volts with each repeater having a Zener of the Voltage needed to power the Repeater in series with the Power. Think of it as a High Voltage supply with a string of Zeners in series with the output, each repeater having it's own Zener with the voltage and current being taken off across each Zener. Quite a simple setup, but it worked quite well.
Useful as always!
Thanks, your a absolute legend!
Thanks a lot for showing me alone a difference
Very good explanation. Thanks
Who is this guy,i have seen mulitple subjects and all of my problems are solved just by one guy,how much knowledge does he have haha
Great explanation, thanks.
Nice explained!
This is great and very understandable
Good video on the zener diode Given the high voltage noted in the DC 50V example, you should have spent a moment to discuss P=I*V and the importance of the power ratings of the resistors. Some novice viewers might replicate this circuit on a breadboard using an improper 1/4W (.250) resistor and be alarmed by the magic smoke.
U r great.....u saved my day 😎😎😎😎
Dude u r awesome !!!🔥
Thnks a lot man💙
clear explanation thank you sir
Excellent tutorial. The zener is underestimated in the age of the parasitical 78XX and it's siblings
I can't believe i took a week to read a book when it all can be compressed in 11 minutes (or even 7m 20s with 1,5 speed)
Well done 👏✔ Tnx a lot. You are the best teacher. 👌
Thank you so much for this.
Thank you very much from France, I had on one of my schematics at te output of one op amp 2 Zeners back to back as you show at the end of your video and I was wondering wat they were for, and now I understand Thank you so much keep going the same way.
Hello
I assume the source of AC signal should be 40v pp to get this output. Otherwise the outcome would be 12.6v pp.
Excellent!
Thanks sir I really enjoy your lecture
Thank you for a great video. You provided the explanation and formula for how one would calculate the current in the entire series circuit but how would you calculate the current in the diode versus the resistor?
How come college professors in engineering can't explain this clearly? I know, it's just a rhetorical question.
They take special courses in making clear subjects unintelligible.....
Мне казалось, что такое бывает только в России. Я ошибался :)
To be able to easily explain something, you must first fully understand it yourself.
@@rozwell69 Einstein said, if you can not explain clearly, you don't understand it very clear.
I always see comments like this. And I always think.. then you've seen it once before then if you mention school. If you (someone) went to college with out any knowledge of the subject beforehand of course it will seem like they didn't teach it to you. Not that there aren't bad jobs done at colleges etc, but don't discount that you have to familiarize yourself with subjects before you can try to understand them.
great video...
thank you....
😍
Very well presented... 10/10
G'day mate, OZ! OZ! OZ!
this guy might actually save my end sems
my university should be giving you my tuition. professors are garbage. thank you so much. my lecture on this after never seeing a diode, was literally...
"ok well, theres a voltage and a current, and its really quite simple lets move on"
no examples, no explanation of anything. without your help i dont know what i would do.
like damn ... i couldnt understand my professor ... but this, makes it look easier
Thanks a lot.
Thank you dear👌
great video :3
thank you for all
it was perfect thank you very much
nice one mate
thanks man !!!
I was hoping you would cover voltage shifting with the zenier in series in the secondary of transformer to drop its voltage by the zenier value. I work with Tube amps a lot and the mains used to be 110ac, now there 120+. I was thinking of adding a 10v zenier in each leg of a center tapped secondary to drop the high voltage.
Thanks a lot sir
my lecturer i love him
Thank you❤❤
Excellent
Good vedio to understand the zener diode in small time
thank you sir, i have decided to subscribe the channel
Aptly great professor... 🇧🇭✌️
Great discussion of zener diodes; I wonder in a processor chip whether these zener diodes and thermistors are the major elements?
