[23rdprime]

WOW ...Mit has so many girls in engineering class.... :(

5:04 hahahahahahaha

[bananinhao]

ok

[agapitoflores001]

I would love to watch more videos like this.

[IwantToLearnWingChun]

@agapitoflores001 do it

[MrPEDOCTOR]

A very interesting video.

[Missmethinksalot1]

Love his teaching style

[jojygv]

Good teacher. I wish I had a teacher like this when I was "learning" electronics.

[darkknightgaury]

I am already an engineer at Boeing and still find this useful !

[dhartin]

nand is "not and" why can't he just say that?

[ImpoliteFruit]

@dhartin Mainly because the NAND gate is simpler to build than the AND gate (and hence often used to build other gates). Also because engineering is about simplifying, so NAND is shorter to write and say than "NOT AND". NAND is the accepted term for the gate as well.

I hope that made some sense. :)

40:42 Actually "I" Flows from S to D Control by G

[EarthlingObserver]

@lobo25usn current flows from negative to positive, from source to drain, you are right. using plumbing as an example is a bad idea because the source of water and water pressure are in the same direction where voltage and current are not.

[DarksideEE7]

@EarthlingObserver

The hydraulic analogy is a perfectly viable example from which to understand electric components. Sign convention in circuit theory is arbitrary, so you need not apply it to that analogy. Simple comparisons such as:

electrical current > hydraulic current

voltage > pressure

resistor > pipe diameter

inductor > paddle wheel

capacitor > small rubber tank

Wikipedia has a great entry on it.....just search 'hydraulic analogy' and it's the first article.

[EarthlingObserver]

So, Mr.Darkside, if Im building a circuit with both pnp and npn transistors, and I'm assuming that voltage and current are originating from the same direction, how do you think that will work out for me?

[MrAditya790]

that was really gr8

[hwarangdrac]

Awesome!!

i loved the Quote/phrase "the porpuseful use of science"

[hassanijw]

he is a PAKISTANI :D

[pagalmadman1]

no, ur wrong.....he is an INDIAN.......his name is Anant Agarwal.....u can even google his name..........

[prabhatpalpal]

Prof Anant Agarwal, B.Tech IIT Madras, India.

[selahia]

@prabhatpalpal 

[saswatdash83]

pakistani profs. are very weak  technically.

Teaching in MIT is not their cup of tea.

[nit323]

@saswatdash83 y so biased?

[MatrixOfDynamism]

@hassanijw No Indian.

[mlsebben]

Poor mouse at 27:24!!! lol

Very good lecture!!!

[pkl2000us]

Really helped

Thanks
