Lec 9 MIT 8.02 Electricity and Magnetism, Spring 2002

All you say it's true but remember that this is a basic physics course. The things you say are surely taught in more advanced physics courses.

has he got a big enoigh black board lol?

thats a diss man :(

hehe nice

I disagree, it does break down, ohms law states that the difference in potencial is linnear with the resistance, that is just not true, the "law" works for a short range of temperatures (with acceptable precision) but the temperature itself depends on the current, it's somwhat like newton's law, it doesnt hold at high speeds, it's not a law anymore. Lewis states it clearly, the relation between V and I, becomes a function of Temperature, and at the same time a function of I since T = funct(I)

LOL

Not only that, his schemes, equations order and hability to explain are also flawless. Excelent teacher, I wish I had him as a teacher when I took Electromagnetism in collage, it would have made my understanding of it much easier

his handwriting is flawless, don't you agree?

How about: One atom is talking to another, and says - "Jeez, I lost an electron!". And the other atom says - "Are you sure?" to which the first retorts "I'm positive!".

I have another great joke, laughed alot first time I heard it.

A scalar particle of the quintessence field is a Quinton, what's its superpartner called?


the Tarantino!

Ahaha, funny physics joke! I got another one. God is reading a book called "Phyisics laws" and he is laughing.

ohm's law does break down and i'm glad it does because if it didn't, we wouldn't have all the wonderful circuits in our TVs and computers : )

Well you could think of it as the gravity law, which only applies for big masses and small speeds, good for most applications but not so good for really precise measurements.
Ohm's law will probably hold precisely enough in most temperatures that modern electronics have to endure, the tolerances on components also add up to the uncertainty so it's not really much of a big deal, digital circuits don't really need the accuracy in millivolts when it's +5 volts for 1 and 0 volts for 0.

I don't like the idea that Ohm's law breaks down. Ohm's law holds, what breaks down is our assumption that the resistence of a particular object is constant.

I don't like the idea that Ohm's law breaks down with temperature. Ohm's law holds, what breaks down is our assumption that resistance is constant.
