Lesson 1 - Intro To Node Voltage Method (Engineering Circuits)

[@joeyf6133]

before you decide to watch this one or choose a shorter one, choose this on. He explains it more in depth, is clear spoken and backs it up with knowledge accordingly

first i want to skip this but then i chose to stay after i saw ur comment….yeah it’s worth it to stay😭😭😭😍😍

Watched loads of rambling videos over the last hour by people who don't really understand anything above the most basic concepts, watched this (and the one on circuit simplification) and I finally get it, Thank you!

[@kingrenny]

The most important part of this video is at 19:40 - 21:20 ... This man literally is giving jewels!! Thank you for your emphasis during those 2 minutes. I leaned onto my own understanding and usually wrote it wrong! But now I understand. ALWAYS treat the current as it is leaving the Node!!

[@salom77]

I can tell just from the way you explain that you really want us to understand the concept. You are awesome!

I wish all the teachers were like you. I mean i have my paper, and i know the rules to not get killed by HV. But with you i can understand anything! God bless and dont kill your soul we need you !

[@ΕΛΛΗΥΦΑΝΤΙΔΟΥ]

I have an exam on electrical circuits and this video literally saved me, I just couldn't understand this method even though I went to class and I studied the book, you are a great professor !!!

[@sotrishalicious9288]

I've watched dozens of videos on the nodal analysis method and this is by far the best one! I love that you don't make any assumptions about what we might know and actually take the time to thoroughly explain everything. A million thanks!!

Your clear, simple,and captivating introductions to all your lecture make you KING of the internet professors. You want your students to UNDERSTAND!

[@josephlai9759]

Excellent, excellent, excellent! But truly deeply what shines above all is your altruism and love to commit your time and energy sharing your knowledge to potentially millions of people throughout the world. I cannot imagine the depth of gratitude emitting from every student that you made out of your generosity and kindness. A teacher with a very big heart. Thank you so very much.

[@bmzaron713]

Wow, great words

[@SlowKlone]

I've never seen someone on youtube explain a topic more clearly, tysm

[@nm1978]

My God, you are the best greatest teacher on earth, I don't know if there is or not anyone else that I know that teaches so clearly in detail, you should be an example to the entire world's education systems this is how everything should be taught , instead of long boring lectures, or reading books that are so hard just to understand what they are trying to tell you, because the way books are written is very official language which I abhor, a simple concept that can take one minute to understand takes hours, because the way these evil books are written , the concepts of science, math and everything else are not hard to learn and are actually fun to learn, if it wasn't for these official languages that are used in all books, I am so sick and tired of them. This is how everything should be taught in all schools. Simple, fun and clear. They should learn from you, you are the best and made a big difference in my life, truly American teachers are the best too at teaching. But offcourse your ways of teaching makes it the 👌 best.

[@epistte]

Im a mechanical engineer and you explained basic elcetrial engineering better than my profs did. Its all starung to make sense to me.

[@greasyJFrancis]

this is great. I was confused about the method til i saw this. very thorough explanation, my professor at UW just breezes though this stuff like it's obvious. thanks!

That was the best explanation to date thank you so much! My 45-year-old going back to school brain thanks you!

[@sliderulelover]

I teach a simpler node voltage analysis system. This video, however, was very good. The teacher did a fine job in explaining the circuit and how to calculate node voltages.

[@pitifullyobvious3036]

This is the future of education and training of any subject even for the poorest thanks to you-tube. The best and most talented teachers can video lessons and any student in the World with a cheap old PC connected to the internet can learn almost anything from the best. Colleges and Universities could become obsolete. The teachers can distribute their lessons directly without needing a classroom and get rewarded via you tube. First learn English as it is the Worlds common business language and the World needs a common language.

I spent a day and a half trying to wrap my head around MITx and EdX explanations, couldn't get it. Watched this (very intently) once, and solved the problems I couldn't comprehend!

[@MrHusseinhijazi]

that was waaaaaayyy easier than when my doctor explained this lesson. she literally messed everything up and you organized them. thanks!

You're saying clearly. I'm a Filipino and watching you. Thank you sir

[@matthewosburn419]

Cramer's rule is also a quick way to solve v1 and v2 by hand once you have your coefficient matrix and b. Helped me a ton, especially when solving 4x4 or bigger matrices by hand that are more difficult to invert. Highly recommend TI's solve functions if you have access to them. Good Video!

15:00 is an important part. You see u need "n-1" eqns to solve whereas "n" is the number of essential nodes

My mind started to get very confused as I have never come across "Node Law" in the 1980's when I was at college. This dude is brillant in expaining in details provided your mind does not wonder off.

Thanks so much for this... I felt like an idiot in class because I didn't understand it. But now I understand well.

[@oldcar8592]

It's been a long time since I took matrices in college, but he gave enough explanation to jog my memory for me to understand what he did solving by matrices. He solved for V1 = 9.74 at 34:26, but mistakenly wrote V1 = 9.4 on the whiteboard. I wonder if he did it intentionally to see if people were paying attention because at 36:30 he emphasized "We now KNOW what V1 is...We KNOW that" and also later while referring to the wrong value.
