Lecture - 2 Diode

[sharad945]

thanks sir i learned in this video about the diode ,

[SuperMuvindu]

thanks india



[poljakov13]

Do i understand right that diode own resistance will be always 0 ohm ? basicly any diode dont have resistance ??

[MrYanny14]

the intro music kinda reminds me of an Al Quaida recruitment video

[podgyhodgy1]

Nice lecture but there is an error. The slope of the graph for 2K should be steeper (as he says) but he then draws the slope shallower. oops.

i.e. there should be a smaller current change per unit of voltage not larger as his graph would indicate. Dont get confused folks.

[AnomisMLG]

R=100mA ? ARE YOU FACKING KIDDING ME ????

R=Ohm FK!

[17stricklandb6073]

3a=2dm^6b+rc6*f2

[originalfizixx]

@ latribe: I have no problem at all with his accent. It's perfectly clear and understandable. Remember, the people who would be looking at videos like this would science types, maybe engineers. They would tend to be of a higher intellectual plane than the average "American" citizen you are apparently referring to.

[JAI1657]

Thanks Sir,

Wonderful Thats great lecture. This is hw the standard education cmes from

[ramialsaiad]

Thank you sir

[tenarify]

R=100mA :) keep up the good work

[tuhinpaul]

@tenarify it's a mistake dude!

[kousami]

Really great job !!!! Please continue the great work...Thanks it real helped me a lot.

[Petelecaster]

I like how he actually explains the equations he uses.

Graphs are also probably the best way to teach electricity.

i find i learn a lot more when people use chalkboards rather than white boards (markers). :S

[sruhan007]

thank Q sir ,really this helped me a lot :)

but some damn fu***** are commenting about accent and all ,those idiots are asked to listen the subject

[gayprj]

A lof of thanks to teacher for a good explanations. It was more useful than book reading. Thank U.

[TheBeyBladeNation]

Fuck up. Using I I pad can't re write comments

[TheBeyBladeNation]

Who cares bout accent he's smarter then you'll ever be please shut the

[Freigeist20789]

now i know why a blackboard is much better to explain things than overlaoded powerpoints presentations

[TheNikmouk]

il a fai une erreur d'unité mdr!! la résistance s'exprime en "omhs" et pas en "mA" regarder vers "5min56"

[TheHassanhass]

very poor accent...............

[HPaisana]

wtf is this, do they learn this shit too? dam muslins

[sruhan007]

@HPaisana STFUp

[338magnifier]

Really good video because of teacher :)! I just refreshed my 20 years old power plant electrician certificate fundamental skills via this video. Have to say that this lecturer was better than we had in our school in Finland 20 years a go. Thank you

[Henbane0]

06:06 R = ? = 100 ohms not 100 mA :p

[FUTIRAMA]

thanks a lot

[nsandeeprao]

its nice video n helpfull



[azkeyz]

A very inspiring old school reminder lesson.

I'm dealing with a salt battery situation where I have 3.8 million ohms 1.2 volts .5 mA

in a single container , multiplied by 8 in parallel , 2 in series

thats 3.8 million ohms per container , I'm starting to feel like I need to put all my electrodes in one container to lower resistance.

what do you think professor ?

[MsTriptisingh]

In linear resistance resistance is having its unit in mA ,is it right

[jaspertax]

isnt v supposed to be U, and i supposed to be I ??

[wasim3s]

Good lecture but their level is very basic.

While sedra & smith have high level.

Floyd-book have normal level.

[donalddaizy]

yes video is too great but it is only possible by teacher.... therefore, teacher is best.

[hausiusi]

This video is great!!! Thanks much.

[TravJacobs]

This video is nothing BUT...

[silerapr]

Thanks, it was really helpfull!! =)

[TheGogo9er]

F*** chalkboards. I enjoyed the video until my ears began to bleed.

Really though, nice job!

[TheDblock96]

Very good explanation . Thanks much..

[zeusapollo123]

awesome vids on electronics!

[Ammarooo9191]

how do this doctor made a mistake like R = 100 mA ,we know that the ampere is the measurement of the current not used for the resistor lol

[starbearer76]

LOL... to the person who wrote, "It's probably Americans who cannot understand this very clear English with an Indian accent."

I get what you are saying but seriously... I'm not THAT retarded. I've been to Dunkin Donuts enough times to understand the Indian accent quite well.

I've watched this video and have taken quite a bit from it. very well done. He could do just a bit more though in doing what the MIT professors do and actually have a real world application demonstration.

[starbearer76]

just don't listen to it on Hi-fi speakers.... lol... the chalk on chalk board sound was captured QUITE well in this video.

[Igpitians]

Wow,

so great...

well job done...

very helpful tutorial.

it can help a lots for those who needs it...

thank you professor...

thank you for UPLOADING this VIDEO...

thumbs-up!

[mrdiceman83]

i have to say that that i learnt more about diodes in this one video then i did in 5 weeks of lectures with the stupid lecture i have at uni

THANKS

[mikehacksdotcom]

1:29 to skip intro

[nethu7171]

WoW What a beautiful explanation.Thank you very much

[Kaulstoessl]

Wow this is fantasic thx for uploading!!! I'm just studying this for my hobby electronics projects and its given me a lot of insight already. Prof. Radhak does a great job of explaining!

[MrPowerElec]

very good lecture, not lot of prof take time to explain the concepst, some try to prove that they are very good by starting with confusing problems and instead of explaining the basics and how they are used thy just confuse you , beautiful lecture

[gummaish]

thnx prof.. cocepts very well explained

[srikanthutube1]

NO need of extra tutions

[bisnu0pagla]

Great tutorial

[szudeme6]

There is a little mistake @6:00 he says ohm but he is writing down mA... R=100Ohm would be right!

[zottelul]

oooh, maaan, its my own teacher but with a color :s

[nasko700]

yeah, I'm sorry, it's my mistake! I saw the 1/10 but later. Can I somehow delete my comment?

[nasko700]

1/pow(10,-3) = 1000 ohms ( not 100 )

[crazylazystacy]

@nasko700 your right but he what he did was 1/10x(10^-3) which equals 100.

[crazylazystacy]

@nasko700 your right but he what he did was 1/10x(10^-3) which equals 100

[crazylazystacy]

@nasko700 your right but he what he did was 1/10x(10^-3) which equals 100

[waldenhouse]

Learnt more from him than I did from my English Electronics professor!!

[glassesization]

also using the sedra book

[oouthuttan]

This might be a session that an engineering student will be looking forward to.Thanks very much for posting this video and i will request you to keep doing the same.Who ever has done it.

good lecture

[saisandeepreddyb]

goog lecture

[Riveay]

Well,

0.5V / 0.01A = 50 ohms and someone wrote the error in the first operation.

But everybody makes mistakes, he's still a good professor and I prefer his lessons rather than a boring book. Very clear teaching manners.

[mrplasma375]

at 6;13 R = 100 oHms not 100 Ma

[MrAsim08]

where i can find lecture 1 which is the one before this ?

[JayFour4]

thank you very much!!

[d0nunit]

Thanks alot

This was really important lecture for me, and I understood it very well, I am using this Diode stuff in almost in all of my classes

and this is only first 50 minute lecture I ever finished on youtube.

Thank you again sir

[sahandsandi]

thank you, thank you

[labas79]

The video is very very very eductional. and this kind of english is very good for me to understand as no nativspeaker ,thanks for this.

[latribe]

Thanks for posting this educational video.

It's probably Americans who cannot understand this very clear English with an Indian accent. I was at a Cannes Film Festival showing of a Clint Eastwood film and could only understand the American pronunciation by reading the French subtitles.

My experience at Imperial College London in the 1970s and 80s in the Physics department were that our Indian tutors were very accomplished. People have to listen to the substance, not the delivery.

[makedonas86]

OOOOOOOHHHHHH saaaccchhaannnaaaa

oooohhhhhhhh

hahahahahhahahahahahahaha

[AntiStalinist]

Clip Shhhh, Clip Shhh!

[HelloBrainMind]

very helpful, and you guys are very sheltered if you can't understand his accent, it's actually quite understandable.

[pcgkhatri]

Non linear register,

In region v>0

For change in voltage=0.5 volt

change in current =2 mA

so resistance in this region is 250 ohm

[prabdude2k64u]

dude i say fuck all u haters who r bitching about his English nd lil errors... common man he's human.. and i understood a lot more than what i did in lecture here in my college.. so those who don't wanna learn - go fuck urself nd leave this guy alone.. and the begining is a prayer so better respect tht.. PEACE !!

[gohomencry]

speak understandable english man..

[mizzxlizzie]

really.........

[RCEbooks]

Oh brother... that music! Jihad.... Jihad...

[RCEbooks]

I know what it is, I'm busting balls ya pussy!

[worseto]

He is talking about physics not calculus.You calc wizards are twisting a mute point.

[WilliamRAlford]

90 seconds before lecture starts

[widdalightsout]

I love the starting :D

[Kazabooboo7]

R= ohms not ma...

[man4hire]

I just took a big smelly shit.

[Georgedegriek]

NAMASTE

[Georgedegriek]

its Said's father on the island a long time ago teaching the Dharma initiative electonic class

[Georgedegriek]

This looks like the Dharma initiative Videos xD

[kashai138]

wassup w/ the music ... o.O

[ToothbrushMan]

Technically speaking, any number divided by zero is defined as "undefined". It is NOT infinity. Makes no difference though, but had I written infinity in my exams I would have been penalised.

[Bissmarkpl]

x divided by zero is infinity

because you will need infinity of zeros to get x

if you put it on a graph the parabole will touch nor y or x axis , infinity

correct me if im wrong

[ToothbrushMan]

Nope. The best you can say is that as b->0, then a/b -> infinity. But formally, a/0 is "undefined". If you start treating infinity as a numerical value, then you can create some logical paradoxes (i.e. what is 0/0 ?). Note also that if a model of a physical system states that a quantity is "infinity", then it is due to a deficiency of the model - no quantity can ever have an "infinite" value.

"So 10/0, at least in elementary arithmetic, is said to be meaningless, or undefined." (Wikipedia).

[Bissmarkpl]

meh :)

[ToothbrushMan]

... and I'm great fun at parties too ...

[Bissmarkpl]

ok... yes you are i suppose

[saidey8]

thats is the worst agurment ever. u cannot any divide any number by ZERO, it is a mathematical error.

[Bissmarkpl]

thats why everybody got over it 2 months ago

took at ToothBrushMan's post whichexplained everything ... 2 months ago

[Georgedegriek]

i think you get the idea pretty clearly though, its electronics, its not strict mathematics...

[OlympusPT]

Thx for this. Good info :)

[eysteins]

Man, this is really helpful. Much better explained than the sedra/smith-book I am forced to use.

[mybloodismetal]

i hate that book man...i read it before my midterm on op-amps, and in the exam i was so dumbfounded man...and my prof was saying this is the best book in electronics...my ass

[didld23]

@eysteins I know it is much better than *ucking SEDRA/SMITH way of explaining..

I think SEDRA/SMITH uses way too much variables and maths that eventually confuse you.. Considering the fact that engineers must use math to understand behaviors of certain system, the book imposes too much physics + math in it.

[goodbyelonglive44]

@eysteins only if Diodes were this easy..1year ago...I am looking for capacitance effects on diodes

[saxoon1]

100 Ohms not 100 mA

[emerxon]

6 min : 6 ohms, not 6 mA
