Very nice, glad you're making use of this material. (Although I am questioning exactly why your instructor is making you use this technique!) Please tell your classmates about these free resources!
thank you very much sir. my professor is 60 years of old and we need to learn this technique. first i didn't like it but after practising it a week i am actually falling in love with mesh and nodal analysis. i think thanks to you and your lectures
My instructor is making the class learn this along with mesh analysis....He totally looks like an engineer from the 50s/60s....(he is) hahaha....my pain is real. But thanks for the instruction. More examples really help!
Oh this brings back nightmares from my Electric Circuits course. I think I'll stick with the superposition theorem, source conversion, and circuit simulation software. Thanks!
I think I may have spotted an error? At 7:28 I got x = 4.2, y = 2.2, and z = 8.8 with the same entries as yours, though I'm not sure if this is an error in the video, or just an error in my calculator settings. Just wanted to mention it, just in case.
Thank you for such valuable resources I really enjoy watching these videos :) at 14:10, while writing equation for current Ia at node Vx. If polarity of 72V source is reversed will the equation be ((Vx+72)/9) ?
Using double subscript notation VAB = VA - VB, where VA and VB are single subscript voltages with some common reference. If the polarity of the 72V source was reversed the voltage at the bottom of R1 would be 72V lower than the reference. Assuming polarity across R1 to be + to - top to bottom (ie: I1 is leaving node A) V1 would be VA - - 72V or VA+72V. The question is ... why do you want to make this problem more difficult? It's hard enough as it is!
My only critique for the second circuit example problem is naming the resistors. With all the conversions going on, notes got a little jumbled being 3 resistors are 60 ohms and the currents are different. But this is still good refresher.
It happened in first year Electrical Engineering at uni, lecture 3....because doing it on paper is cheaper than using software or, God forbid, actual components.
Beautifully explained, you are saving my cgpa

So far these videos are the most clear and concise videos I've seen on circuit analysis. Thank you.
Thanks! Please tell your friends these free resources exist.
@@bigbadtech Already told my backpaper friends about theses resources thank you so much, you make things cleaner to understand.

Finally I feel I'm not the only one that feels this way, I would rather have my students learn how to use LTspice

Check your signs. x=5.8, y=6.4, z=11.4
@@bigbadtech Oh yep, i see what i did wrong now, thanks!
This guy is informative and entertaining, loving these videos

You are right I'm bored but not suicidal. I'll skip this one
bob brawley Wise choice! Here's a skill that yields the same results with 80% less chance of suicide ... th-cam.com/video/19Ft6CzdHHU/w-d-xo.html

Tricky tricky
ain't that hard...
