Lecture - 10 Transistors

[Orthosonic]

15:57 TO-221 should be TO-220...

[sgtborup]

This man knows his stuff, keep up the good work !

[khalidmotors]

I never seen this type of excellent lecture on Transistor anywhere. I salute Mr. T.S.Natarajan for this marvellous effort. This is very help full for me to understand the Transistor behaviour and operation. May God live you long with happiness and health.

[rahulsabikhi1]

faaaadu lecture :)

[MySPARKIE123]

wow yen pee yen

[aptsys]

yen pee yen

[coolbro187]

that guy is a good teacher he explains shit really well and its not his first language. what a beast

[dmanaga]

A diode is an active device ( Active device - can amplify and/or rectify).

[hospitalbedpan1]

I'm so glad I watched this specific lecture.

I always understood how to "solve" amplifier problems, but I never really understood the whole concept of "N" and "P" with the forward bias concepts until I watched this video.

Good job :-)

After watching all these lectures, I'll be ready for my certification early next year. And by the way, I'm writing this message from Miami, Florida.

[gagandeep426]

it is realy very good

[Iced0826]

This is probably the most educational video I've watched on YouTube. Thanks, professor. This is gonna help me in my engineering class so much! :)

[thechildofuniverse]

OOOH MY GOD :)))))

[1212dorado]

no sean culeros pongan subtitulos a español

[azkeyz]

Transistors accomplish the amplification by using another power source

more accurately we should refure to a transistor as a switch first , amplifire second.

[Americanhero4]

Hi, professor

can you tell me what simulation software are you using?

or can you send it to me, please!

Thank you very much!

[overfarhan]

@Americanhero4 i also need that electronic simulation softwere used by Professor.

[eet0505]

I have an associate degree in electronic engineering technology and this video is a lot of information for being on you tube. And I learned a lot about transistors that I didn't know before. Thank you Dr. Natarajan for the information.

[o2tosin]

Thanks Prof!

[VanPhoenix24]

thanks for the video Mr. Natarajan, it is very informative and quite easy to comprehend. although the accent is noticeable, i already start to get used to it anyway. by the way, can i know the simulation software you are using in this tutorial? I'm curious about it. thank you.

[LemonInYourEye]

yen p yen

[UberTroll13]

what is this? all i heard was something about curry

[sudhanwapanse]

very very nice concept clarification

[miyukiTS]

The university seems like a religious sect from India.... hehe ... but it knows pretty much about electric stuff ... Ohmmmm ... Ohhhhmmmmmm ..... the holy god Resistor,,,, ohhhhhmmm.

[TheOneToxic]

why is electronics popular in india ???

[rimbocha1]

really I'm proud to be an indian

proud of our iits and iisc and truly grateful to their efforts

no other institution has taken such effort

[Kaulstoessl]

Thank you for the upload, very nice lecture!

[dhuptube]

Thank you very much for the lecture Mr Natarajan...I've been up all night for understanding transistor, you just made my life easier...Thanks again...

[cesarambula]

Namaste Professor:

Thank you very much for your videos.

Everything is very clear to me, I am from Mexico.

No problem with English.

Thank you.

[mrjagan1]

you are great prof i think you should come here in italy to teach our prof :))

[WorkFromHome001]

Unclear English.., nice try though! Not the speed your are speaking. it is the CLARITY which is poor.

[Mushketer888]

as more times i view this - as more i understand :D

strange :D

[semoranman]

Lecture was very well done. Thank you.

[SuperMechtronics]

I appreciate Prof.T.S Natarajan for explanation in great professional way.With this kind explation we can use this knowledge for our practical applications.

[aafrika0]

I learnt two thing from this lecture.

In india people call Circuit, Sir-Cute

And indians ride elephants....

THUMBS UP!!!!!!!!!

[urbandiscipline88]

@aafrika0 lol

Same here

[tommeasor]

"This person speaks much clearer than most people from northern England"

aye Speak fre yorsel mun

[pbfuddle]

I also appreciate this grand effort by Prof. Natarajan! Thank you very much.

[igotenchicks]

who knew i would actually understand the "disection" of a transistor! that was really cool i always wondered what those little guys were, now i guess i can watch it all over again and do some hands on stuff> thanks> i plan on watching the rest of all his videos_ you gotta love how he breaks it down into simple examples like plumbing and finding yourself on a map :)

[komal10492]

That is indeed very nice of you sir, to share your knowledge and help many who are befuddled with the subject.

i have a query:

how does connecting a resistor across the collector and the base ensure that the base emitter junction is forward biased?

[youngdones]

There are Hundreds of Millions of these in my CPU?

[Flashanimator10]

@youngdones yeah but those from your pc are microscopic .not that big

[19ultima88]

What is the name of the programme used for simulation? I am studying electrical engineering and now is my 2nd year is british uni and until now I didn't know what transistor is!!! This is the way you teach!!! Thanks a lot!!!

[mohitkumarsagar]

thanx very much sir

[lutownica1]

Thanks a lot profesor. I like th way he conduct this subject.

[hyperloke]

very very good lecture. helped a lot!

from Georgia Tech

[manthrikan]

Excellent..Excellent... Excellent... Excellent... Excellent...

If this was the way the subjects were taught in colleges, we'd all be scientists !!

Only Indians will give things like this free ;-)

[manthrikan]

Excellent..Excellent... Excellent... Excellent... Excellent...

If this was the way the subjects were taught in colleges, we'd all be scientists !!

[maramajay]

thnx allot..........



[villian1987]

Thanks allot sir for your contribution on free online education mr to bhagat ho gya aapka

[rolynbesmanos]

I'm planning this second semester to TAKE ELECTRONICS ENGINEERING

so thank you very much prof. for here I can study in advance

[smile0dont0cry]

thank you very much Pro.

very clear ^_^

[Yami7761]

best teacher in electronics

[AxelTiger]

Ive been into electronics for years now and im still tryign to get my head around exactly how a transistor works ha ha!

[cortexedge]

@AxelTiger the same here ;]]

[tom92373]

starts at 1:18

[sixstringmania]

after years ive finaly understanded the basics of transistors the correct way.Theres no comparison to the way we did it in schools here in greece.It was only blaaablablabla and a bunch of math..

You are a honorouble person for doing this for free (as knowledge should be all over the world)

[kaferere]

I like the intro music, Ohm.......Ohm.......Ohmmm. A resistance song? Great video thanks.

[kandoigaurav]

@kaferere hey....its nt a resistor song..!!

bt itsss for aum..!!! its beleived in mythology tht d world originated frm this word..!!! it has gt immense power in itself..!!!u cn google it out..!!

[kaferere]

@kandoigaurav I think my joke went above your head. I am perfectly aware of the buddhist trancendental chant of "ommm". You however don't seem to know that an "ohm" is a unit of electrical resistance. See the joke now? Penny dropped? Resistance song? Unit of resistance? Get it ? Anyone home? Anyone ohmmmm?

[synapss21]

ah diarama that mean thank u

[RFXCasey]

You have to be careful cause he seems to be teaching conventional flow as opposed to electron flow theory. This can confuse you if your not aware of it and even if your are it's still quite confusing. Still good stuff though.

[Edutroniko]

Tu ingles es re contra MALO

[goodinvestor]

Fantastic! IIT is emulating MIT in disimenating high quality knowledge.

[tajiknomi]

hay guys...I have NPN transistor TO-92 package....

How can i find the maximum Voltage to operate it on Collector & base..??if some1 knows....plzz reply me...........max Operating voltage & current..>>???

[RFXCasey]

@tajiknomi

You need to look at the data sheet for that particular device. It's a good idea to have catalogs from sources like Digikey around for reference purposes.

[xato909]

@RFXCasey lmao xD

[RFXCasey]

@RFXCasey Well, with the online catalog all you have to do is punch in a part number and they usually have a link to the data sheet right there. It helps when your looking up info on many parts quickly like if you recycling components out of old equipment. Sure beats going to each manufacturer website individually. You can download the PDF version and keep it on your HDD. XP

[julien4able]

thk u teacher! your explanation are self explicit n have help me a lot, ALL THE BEST!

[gordilloedwin]

damn,..i cant appreciate enough the time the prof has destined to our education but my poor english combined with his little fast accent dont quite mix up, either way i had to watch it 3 times but i finally got it , thanks!

[paralogos]

Someone explain this to me please, at the mic / loud speaker example he said that we're getting a current amplification while a while ago he said that we're not getting a current amplification using this connecting but we're getting a voltage amplification. What did I not understand?

[aresrosu]

Thank you very much for the lecture! It has been extremely helpful. My only wish is for the video to have a better image quality...I can't always understand what has been written on the screen.

[qwertyma733d]

Awsome sir !! u solved my problem !! thnk you !!

[middleeaster]

:awsm: Thank you... again

[colombus272]

Very informative and explained in a very simplified manner so that anyone who has a aptitude for electronics can understand. A very big thank you for posting.

[XE1GXG]

Interesting and useful.

[maksimos123]

thank u for the lecture

[wilfergalsen]

najantacan culincancun mujeriegon electronics cusejaton

[MattUK2007]

Excellent video. Learn by doing works.

[juplacen]

I do not understand this indian guy!!!

[juplacen]

Get rid of the introduction!!!

[iorixs]

probably the spirit of the intro that inspired them to post these vids

[middleeaster]

Superior lecture as always...

[tonyshit80]

ommmm......Namashivaaaaaaaaaay­aaaa

[UserIsAnFBIAgent]

The part that I'm having trouble with is starting to be explained at 19:23 >>. How to connect the damn transistor, because after all, the transistor has freakin three terminals, not 2 or 4, which makes it very hard for me to comprehend how to connect the transistor so that it can amplify a signal and then output it.

[Mushketer888]

best electronics tutorials :)

[accabog]

thank you :) better explained from youtube than in school

[casperika]

thanks so much for posting this useful lecture

[constcon]

This person speaks much clearer than most people from northern England or from southern USA.

[anothershakey]

@constcon define "clear" ...

[snedie69er]

@constcon

You mean Scotland?

Scotland isn't part of England, it is part of Great Britain. :)

[gollumondrugs]

@constcon Where are YOU from?

[ismeto]

ugly boring voice. subject is good and thank you nptelhrd. but their english is not good

[taou]

EXCELLENT PRESENTATION THANKS

[nlloyds]

all this crap is starting to come together and make sense thank you, this was very helpfull

[mankenavenkatesh]

this lecture is really useful sir.thank u so much for ur benevolance in presenting this kind of lecture series

[earthwormjim3D]

circute...lmao

[ikirun]

The word is circuit--from French and Latin. His pronunciation is more proper than yours. So...I'll laugh right back at ya, Mr.Wanna-be-a-jerk.

[ikirun]

Earthwormjim3D. That is exactly what you are: an earthworm. Blind and deaf for first and foremost failing to notice the gender of the lecturer. A hypogeal creature without the ability to know anything beyond the surface of the lecturer's accent. But--then again--I am being unfair to the earthworms by comparing you to them, because even those creatures have a purpose.

[nald623]

Very good discussion on transistor.. The actual application really impress me on this lecture... thanks for sharing your knowledge Professor!

[szlamx]

Woltage?

[emjohnsn83]

Appreciate all professors who take time to share their lectures and notes to the world FOR FREE.

To save time, you can go over this lecture faster but still get a good understanding of the concepts with MySpeed Enounce.

(If you do not understand Indian accented english too well, you can also slow down the video with enounce myspeed.)

[himalchulicup]

his voice blasted my speakers

[mindsoulbody]

p yen p or yen p yen transistor? XD

This lecture helped me a lot. Extremely informative.

[castrofocobiana]

kudos

[tehpwnereryeah]

i can't understand what he's saying, majority of electrons and majority of "holes"? are these free electrons, i don't understand

[rurzan]

en wikipedia org/wiki/Electron_hole

[ichbintharaka]

Knowlegde has no language barriers.. Well done people.

[ufoseverywhere]

american proffesors enyy this! lazy bastards! always leavin the class for "paperwork" Yeah, toilet paperwork

[beou1980]

this accent really turns me on!!!!!

mercyyyy!!!!! hahahaha

[ozzez]

que dice???????????

[aviatorgtm]

awsum job prof....

[nangbutinang]

Thanks a bunch 4 posting all these!!

[sinsagoodmansbrother]

This is an excellent presentation. Thank you for posting this. I will be using this lecture to train a small group of technicians about transistor theory. Very well explained!... Thank You Professor....

[consolechat]

Lol im in ireland, being confused to hell by my electronics lecturer,and an indian lecturer is helping me out.... kindof funny what the internet can do 4 ppl

[bishwok]

awesome lecture!this is the reason for my sleeping in the class!

[pranavashok]

This is just great! I never knew transistors could be made this simple and interesting. Thanks a lot Prof. Natarajan!

[EulenthalKruemel]

Thanks, Professor. This is great meterial - I will recommend this wherever I can.

[Fleischmahn]

Lol, he says like "Yen" when he's supposed to say "N", but who cares? It's a fucking good lesson.

[dodecalogue]

I am supplementing my ELT classes with these and the MIT opencourseware lectures! It works so well!

I really like these lectures, very good job Professor!

[kyokushinfighter78]

Fuck! Learning this is much more useful than staying in my class for one god damn semester !!

Thanks Prof Natarajan!

[romuleezey]

Very helpfull but I can barely understand -.-

[shankotte]

thanks for the person uploading this video

i will downloading in my pc

thanks for aprofasor

[googlyeyes9292]

i havnt watched it completely yet,,,,,,but i'd say its much better than the lecture back at my school,,,,,,,,thankss,,,,,,,

[xxxslickslayerxxx]

awsome video, very informative. I'm using this for studying.

[scfcrmint]

This is amazingly helpful in gaining understanding of how transistors function. I do wonder how this is available for free as it is extremely good material :D

[shivarocking1]

its india

[fambay6470]

Do you have lecture about PLC and PLC programming(programmable logic controller)?

Thanks in advance!!!!!

[fambay6470]

thanks for uploading this video. he spokes very clearly unlike the other professors and lecturers who presented a topic....

[gperaga]

very good!

[chaithanya500]

i am very thankful to u sir , its really a gud video.....
