I wish MIT could release a new version of this course. Not because it is out of date, but because it would greatly improve the quality of the video and text on the board. Also, it could add a lot of new knowledge from new electronics we developed in this past few years
I think Edx has an updated free version
@@RahulT-oy1brwhat is edx?
@@redage9759 just checked. you get 4 days of course access and incomplete materials if you don't pay. it could even be a scam, there's nothing I immediately see which suggests accountability, and that it's advertising the course as starting today, now, make sure I enroll right away- ... it's sketchy.
"studies show people who pay are more engaged and motivated to complete their classes" well yeah, that's because you rip up their textbook and kick them out after 5 days if they don't.
OMG at 38:30 there is a person who i believe is explaining for the people who cant hear , such a wonderful institute , and i got to know about this now , hatsoff to the best institute on the planet , for the best experience for everyone
I feel blessed for being a student of the era when internet is there..

This is very good lecture to understand the basic current flow in mosfet and fermi level is responsible for current
you have to thank the engineers to have used Maxwell's equations purposefully :)
Really blessed
Yes indeed
@@outrospection4all
O
this lecture was 12 years ago, interesting how technology has grown a lot since then, but this is the base of all this progress
this is way better than my teacher from now
it was actually more than 20 years ago
this guy isn't just an MIT professor. he's one of the folks who heads an outfit making those 72-core microprocessors (among a great many others). the ones we use on our cloud core routers. this man is impressive!
Now he is the founder of Edx: an edtech startup which offers online courses likw CS50 and many more
Wow this guy is a great lecturer. Thanks Prof. Anant Agarwal and MIT
"We could go the hard way and do Maxwell's Equations and get a Ph.D in Physics, but we want to do it the easy way." (c) The Professor. I like this guy.
Hello,
Are you still active?
@@vanshvadhwa2525 LoL he's dead😂
RIP sir 🙏
RUclips needs FAR more materials lke this.

This is good lecture to understand the current flow and about fermi level
hi guys, the greatest success that I have had was by following the Gregs Electro Blog (i found it on google) without a doubt the no.1 info that I have ever tried.
GOD if we had a teacher like this everywhere, so many people would want to become engineers.
I am in love with how he creates the whole vignette first and then starts off. Builds up a map in our brain as to where we currently are.

This is good one
My biggest regret in life is that I wasted my youth instead of studying. Thanks mit for putting these great lectures online. Im making up for lost time
That's just studying in a more interesting subject.
me too
He is such a great communicator. I came here to learn about circuits, ended up learning how a teacher tries to explain something to his/her students
What is engineering... "How to make what you want from what you have", or the "art of the possible"
cooking?
This sums up my whole engineering/science/ freaking educational journey so beautifully I want to cry
He is the CEO of edx 😱 ❤️❤️❤️

Thank you MIT! How generous you are to publish high quality videos like this one for free! Even though there are complaints about the poor video resolution, it doesn't matter that much to me. I can see what the professor writes and the graphs. Just being thankful to be able to watch this video.
Totally agree; some may not realize what a privilege it is to watch the entire course of 6002 taught by Prof Agarwal; I have had his textbook for years and didn’t realize that MIT put his whole lecture on RUclips for us to learn and enjoy. He’s so very passionate about his field. Well for CS majors maybe it is a good idea to take 6002 after 6004, as it will teach us to appreciate more of all the human ingenuity and hard work behind the stuff we touch and use everyday.
what an elegant speech !!!
i feel very honored that i can get a glimpse inside of the forbiden city ( mit )
i can only imagine how wonderfull must be to be a part of MIT !!!!
It’s really cool to watch this kind of lectures while going through math and physics courses - motivates to learn all that while dreaming about times when you’ll just simplify, simplify, simplify 😄
Why does MIT breed great engineers? Not because they are smarter, they have excellent teachers. Who knew?
"What the hell am I going to use this stupid math for later in life!" .... I can remember saying that OH SO MANY TIMES as a child. Now, 35 year old... OH, THAT'S WHY I NEEDED TO KNOW THAT MATH!
.
Pay attention in class kids, stay in school... that "Stupid Math" is what makes up about 100% of the material objects you treasure so much. ;)
Lol
A common failing of mathematics teachers is not to relate it to the real world. As a 12 year old, I could never have hoped to handle differential equations related to engineering - but being shown how being able to solve a quadratic with my eyes shut is part of solving a differential would have made me understand why I should learn how to handle quadratics with my eyes shut.
the short summary: electrical engineers work off abstractions that pile on top of other abstractions, so things get easier as you go along*;
demonstration of current vs. voltage for a lot of common discrete components (including a zener diode);
and "what happens when you feed 110V into a pickle?"
* I note that historically, I think Maxwell's Equations postdate some of the more basic "laws" which are sub-sets of Maxwell's; so he was working towards a more complete synthesis. Additionally, some of the abstractions have their own distinct grounding in other disciplines, i.e. using a programming language relies heavily on mathematics which is grounded...in some way.
Nerdo( weird and nerd)
so well organized, explained, excellent classroom layout, and simply stunning instruction. i have two assosciates degrees in engineering and have covered all of the material covered in this lab minus the in depth maxwell calculations, but nowhere was it broken down to actually make more organized sense - i actually learned a few things. wish i qualified to go to MIT!!!!!
I use these MIT courses to supplement my formal education. I am 40yrs old and working toward a Bachelors degree in Electronics Engineering Technology. My professors ask me all the time why I am not going for my Engineering degree. Unfortunately I can't go to a B&M university to get a degree at this time because of family obligations. This is helping me get the knowledge I would get from B&M.
respects man
Wow this idea of abstraction is so cool. Honestly this perspective of learning physics is so cool. I am an undergraduate (freshman) and I to this day wondered just how an earth can you make something from these simple equations but after how the sir had explained it gives a little bit clarity. This approch is definitely helpful. Thank you sir and MIT for sharing this😊
It may be worth mentioning that Physics II and Calc II are pre-reqs for this course, so this would typically be a 3rd or 4th semester class.
If we had professors like him who could make education so much fun in every college, there would be no drop outs from boredom.
this guys a rock star this is fantastic;D :D maximum respect
at 25:52 where he sets del q/del t to 0 is profound. Like hes constantly restating, you simply a complex concept down to simpler terms, even if that means looking at more specific cases. Setting it to 0 makes the equation simpler and limits the number of cases wheres thats true. As a result, we get closer to some tangible that we can utilize to make something practical.
i can imagine an 8 yr old genius watching this and taking notes xD
If I'd had MIT RUclips 41 years ago, I would have been GLUED to it. Fuck cartoons.
@@Ensign_Cthulhu That's what you say in hindsight with your mature brain but it's not the case when you're actually born into the generation that has it. Proof- well clearly most kids these days aren't actually flocking to MIT lecture videos ahead of cartoons, so how can we assume kids from the past would?
Nice presentation. Very energetic and engaging. I am so glad our higher learning institutions are finally posting classes, for everyone to view.
I love the way you describe abstraction. This is a great lecture, sir. Thank you
RUclips needs more materials like this .
@amodedude yeah, this is the first time that I saw applauses after a class for a professor, this professor is awesome. And definitely one of the best lectures that I've ever seen.
Thanks MIT for sharing these lectures, love every single one of them.
Awesome, Enjoyed his teaching.
Thank you MIT & Anant Agarwal sir.
He is a great lecturer .. gained a lot of knowledge from him .. thank you Agarwal sir ...

Made with HARPA AI
We do all of the adding, subtracting, multiplying and dividing by using attenuation, or amplification. Ohms law and filtering. So, we set up our broad band amplifier's inputs, each input has a filter array option, we set the presets and send a series of signals on a group of frequencies and do all of the math by converting digital to analog and then back to get the results. Quantum, pew.
what a wonderful Handwriting. But a very good teach
If you want to watch these videos in better quality, there's the same course in edX made by the same professor.
link please!
link please!
@@NphiniT Search for "circuit and electronics edX" on google. First link
@@FelipeMedLev Thanks man!
I have been struggling about not understanding the basics of equations. And I've just realised we can be not understanding them but can still build good stuffs
I am blessed to see and know the content of the M .I . T 's open courseware .
Don't let Quantum Computing fool you, or confuse you, it's easy. Bottom line, the answer is next too your TV, it's the cable box and multiplexing. If you convert digital to analog, and plan for a long list of re-iterations, we've already done that with a large number of synthesizers. The EMU chip set but, they don't operate in the GHz frequency range, where all of our capacitors and inductors could be etched on chips.
Old but gold.❤❤❤
Thank you so much, this was SUCH a great introduction, can't wait to watch the rest!
I wish i could learn at MIT, so much better engineering than where i am :O
you technically are if you're here!
Sonny Huynh Lol its better than literally everywhere. They don't know how to teach worth a shit at public school or my home university. This is a gift to the world.
I can feel you dude, same struggle or even worst.
it is really helpfull for students to gain more under standing by these videos
Great lecture! Thanks MIT.
how is it that stupid completely pointless videos can get over a million hits? STOP WASTING OUR BANDWIDTH WITH LADY GA GA! Thanks again MIT you have shown you truly care about spreading knowledge rather than holding it hostage. I can't afford to attend MIT but now all people need to invest is their time and dedication to learning. We're all in this together people, lets solve these problems.
This should be shown as a manual for teachers. He made it so exciting.
this is awesome. Thanks to MIT for publishing this.
9:53 this key point should be taught to more people
Please also teach how actually uniform electric field gets established throughout the circuit and cause steady current
Just for the guys who'd like to know.....he's the ingenious Indian Prof. Anant Agarwal....he's brilliant !!
The way these guys teach is great.
This guy is a great teacher
Helping me get through my own electronics course
This course is just phenomenal.
13th July 2015 , I started this lecture for the first time. Didn't go past 8/26 then.
29th June 2022, attempting to restart and finish it this time around.
Wow im in High School and I learned much from this video.
He's an amazing Professor!
Now which class r u study ing
@@nandabrahma8679 just curious - What about you
That was great
Thank you dear anant Agarwal and MIT 🙏
I love his energy!
@RapperD9 : This is electrical engineering 1, a very good place to start. MIT organizes their courses by number. Go to their website ocw.mit.edu and look at the cirricula. You can get an entire college education just watching these videos and doing the homework.
This is awesome. Very easy to follow, and interesting way of teaching.
If you watch a wide variety of lectures and take note ,watch this process.You make notes on many different topics.Then you will get excited about some more than others.The ones that pull you in you then write down specialized words of that occupation or what have you.I guess in learning I am lead by feeling.Possibly not right away but when I get the labeled sensation I know I think that chance is good sometimes so I let it roll.Hey how about you.Will you too let i roll,see if the chances aregood
The teacher is excited with his teaching, which is very interesting to listen to.
Best Indian professor at MIT so far.
in the final year @ my High School and I hope I get a chance for undegraduate in MIT. Love to be studying under profs like this. :)
A very active teacher, he teach in a good but also regularly funny way. Great!!
This so much better than these proffs giving out candies to kiddies. So much easy to watch and learn without any distraction of candies proffs.
If the cameraman paid attention to these lectures he could join as a TA next year :P
MIT should please re-record these important videos, so that we can have better video quality. For example, I couldn't see what the professor was showing on the projector.
Amazing introduction to the subject. A great way to harness interest of students.
Inducing interest in learning should be the primary goal of every course in uni.
This is better than discovering gold.. Thank you prof. Thank you M.I.T!
I LOVE MIT!
Hi from Italy
most reputed university with poor camera
Sorry, the videos are from Fall 2000 and were converted from quarter screen Real Media files. The final edited versions were not saved. We would have to re-ingest and re-edit the videos to improve the quality. There are currently no plans to do this since we prioritize the capture of new videos over rework of older videos.
This professor's lecture is so useful. So why doesn't MIT record his recent lectures on the same subject and replace these videos with new ones? Did Prof Agarwal quit teaching this course?
It's free dude. You get what you pay for.
What?
i guess mit had good cameras in 2008 (or 2007). But the culture of conserving lectures just wasn't where it is today.
Note: Gameboy Advance camera was used to record this lecture.
It is so sad to see boobs, booty, and bling bouncing and shaking to some non-sense verses in HD; while the building blocks of the universe, society and what allowed the word "HD" to actually exist are treated with low quality. Still MIT exceed everyone's expectation just with the simple fact that they are willing to share. MIT is not only smart, it is also kind! :D
One of the best lectures, I have ever seen
Great video, but one thing that tripped me up at first was the vertical IV graph for the battery at 33:45. I had assumed with the previous graphs that voltage was the independent variable and current was measured across the component as a function of voltage. This method obviously cant produce the vertical line graph. It didn't make sense until after I read this in All About Circuits:
"If you have a device that supplies voltage or current, such as a battery or a solar panel or a regular power supply, you cannot change the voltage across the device, because there is a specific voltage or current being generated by the device. For these devices, ... [the voltage and current are calculated by] a method that involves measuring the values supplied by the power source for varying load resistance."
For me I visualize this as a third invisible axis of the graph, load resistance (R). R is the independent variable that's varies and I and V are both measured with respect to R. The R I V graph is then projected onto the I V graph in the lecture.
Thus I understood the ideal voltage source would have a vertical line IV curve because regardless of the load it will maintain 1.5V and supply 1.5/R amps of current. As R varies this produces a vertical line.
Another way to think of it is the independent variable is current and voltage is the dependent variable. The graph answers the question "If we force the voltage source to produce I amps, what voltage will it produce it at (if I amps is even possible)."
Let me know if I misunderstand anything.
From what I've seen, high-end Universities such as MIT have much better professors than other universities, including mine.
Difficulty of courses should not be how you judge the quality of a university. Any university can make their courses hard, however without good professors students all fail or come out knowing nothing. Better professors -> better students -> better graduates. Keep in mind this the FIRST day of an INTRO course. Get an EE degree, then come back and say the material is easy.
Awesome professor, very good at teaching.
Marco Caruso he was from IIT kanpur India
I taught electronics at universities and I think this is a big step forward. It leads to the following essential questions however: First and most important - why do we need MIT (or any other university) now that these lectures are available to the entire world? Why can't any viewer now apply to take the exams? Then, with media technology what use is a blackboard? Wouldn't a good animated flash presentation be better (particularly if it cut to real life apps & demos)?
I love MIT. Wish I could attend their electronics eng. courses there instead of ITT-Tech.
wow this is awesome, now we all have access to MIT courses !!!
it's even more amazing they provide subtitles :D
Great definition of engineering ! Accurate, clear, concise, and powerful.
The Best Lecture I Never Had Part 1
This guy was on the team that designed one of the latest generation SPARCs
I wish I knew that MIT pod-cast their lectures before I started studying electronics at my uni :D
Greetings from POLAND!
Prof. Anant Agarwal you ROX!
So insightful! We should always have the importance and f the power of abstractions at the back of our mind.
I am a computer science student and i am totally awed!
"Anant Aggarwal" Indian Institute of Technology Madras ......
He is amazing
Thank you MIT
Highly recommended... this is great stuff.
Best video... I am blessed that I have a phone with internet..
This is the way things work, simple processes making complex machines.
Maybe that is your view of what the top-notch universities are. To me, these universities are places to get a BETTER education. Could you learn the material without a professor? Sure. However, you cannot compare MIT to a vocational school. The material you learn in the higher end courses are not the same. Vocational schools do not go as deep into the material/theory as a university. That is the difference. A car mechanic is not the same as a Honda design engineer.
This lecture should be watched by any aspiring EE/CpRE.
The perspective of abstraction shown here is lost on many when they are studying the details of all this stuff.
This is pure gold!
