Pretty good comments. Great!
@eddiea6987 Indeed you could. Through the point of this analysis is to determine unknown voltages and currents without having to physically measure them. For something like voltage regulators, it’s just easiest to physically measure their voltages.
I clearly have no academic background in EE this is coming from my very new hobbyist perspective , try not to chastise me so much sir. but constructive criticism and corrections are very welcomed
@davestoj i mean if i have a power supply of 12v , then further down the circuit a voltage regulator outputting 5 volts and further down an even lower regulator giving me 3.3 volts , and if i did not know the part number of the regulators and needed to find out how much voltage is going through a certain point/part of a circuit couldnt i just stick a multimeter to the regulators common grnd and output pin and thus get how much voltage is going through that part of the circuit
@eddiea6987 What do you mean by a voltage at each point? A voltage is taken as a difference in circuit potential between two points on a circuit; voltage is purely a relative quantity.
the english subtitles are out of sync. how can i synchronize it. or is there a .srt or .sub file for this course?
@eddiea6987 and current as well
cant you do all this with a multimeter and get the voltage at each point?
@legendmove 22:40 Just like he said. Since there are 4 nodes making 4 equations we use only 3 because the forth can be derived from these three. If you check the nodes you’ll see that these three equations cover all elements. Why would you need a forth one then?
epic moustache
Why there are only 3 KCL equations and 3 KVL equations? In lecture notes it says there are one redundant for each but I don’t get how they are redundant.
Why these 2 are redundant?
I0+I2+I5=0
V4+V5-V0=0
Fantastic lecture, thanks!!
@starbearer76
google mit 6.002
anyone know where coarse notes and or texts books used in the class can be found? what text book did they use?
Node method begins at 33:05
Instead of watching tv shows, i am watching the courses that i wont study in my undergrad curriculum for fun. They are exciting as any scenario, actually even better because they enable me to write my own life scenario. Don’t think they are tiring much and they are broadening my understanding in a way.
As a physics undergrad, i will have some introduction to electronics but still i think understanding thought process of engineering branches and other sciences does only good to me. Free,easy,fun.
Please thumbs up if you would like to see Prof Agarwal to teach more opencourseware electronics classes.
@NAGRAL very happy to donate my money to keep mit ocw available for you for free !
this educational theory seems to follow the star trek (picard) theory where as people take high standards of education for the betterment of mankind not for money or selfish reasons, in a world where currency has been done away with.
Thanks MIT
)))
@Indrid77 go to ocw.mit.edu, find the course under electrical engi and materials as well as the name of the text is there
What is the name of the text book being used for this course, anyone know by chance
what does any of that have ANYTHING to do with THIS video?
@mocatz187 I think American students are behind because they are spoiled and immersed in pop culture. When I walk around campus, all I hear the American students talking about is their social lives and where the next party is. The foreign students are always talking about tests and subject matter.
It is true that American students are behind. Thats because they spend so much time indoctrinating our students with communism. Business and industry is now seen as evil here in the US. Our department of education has been getting rid of stuff like this.
In foreign countries engineers are admired here we call them geeks.
We are being destroyed from the inside out, then they will come for you “third worlders”
