At 5:00 the matrix is available. From there you can go and input the matrix into MATLAB, or do this by hand and find RREF. This will give you the values for all unknown currents. I can share my project report I am working on that explains a lot of steps. I note in several places extended details and explanations and step by step row reduction to solve. Also, in most linear algebra books, RREF, reduced, row echelon in matrices/Gaussian elimination is explained in Chapter 1.2. My textbook is Linear Algebra with Applications, 9th Edition, Steven J. Leon. If I had not learned matrices well this semester, I would be confused too.
I hate to be that guy, but if I5 = I6 + I3 then 1 = I6 + 0.5 --> I6 = 0.5 But also I2 + I6 = I1 then 0.5 + I6 = 2 --> I6 = 1.5 There's a mistake somewhere :/ I think it's at I3, because current is going from B to D thanks to source at L1, but also going from D to B thanks to source at L3. If i'm not mistaken, you have to take that into consideration. Feel free to correct me, i am curious about the correct answer. :)
Hi Martin, the answer I have is consistent with the source the question was acquired from. That's one reason I was confident with my solution. Though I will double-check the work when I get a chance
I'm very sure it's [i6] (outgoing current at node D) equals [i5 plus i3] (incoming at node D) As a video that's supposed to be educational, this slip up is terrible. And he's insisting that there's no mistake.
you didnt use matrices you should be honest and say you didn't know how other than choosing a problem you can solve without matrices and I think you messed up a few of your equations
Why did I watch 5 minutes of a video called "Use matrices to solve electrical circuits," just to say "nah we don't need a matrix to solve it" and skip the matrix? Maybe rename the video "solve circuits without matrices" so you don't waste more people's time.
As an ADHD sufferer watching videos to try and catch up in class, your addition of "LIKE" and "GO TO WEBSITE" and all the other visual clutter made your video unwatchable for me. Also, the title says "Use matrices to solve electrical circuits" but you didn't actually do that. Sorry, but this is one of the very rare thumbs downs I give.
"Use matrices to solve electrical circuits"
Doesn't use a matrix to solve for it.
Literally this.
It was much quicker to use a matrix.
literally. waste of my time. trying to figure out how to use my calculator for this stuff.
Dude said how to use mareices and litteraly doesnt do so. A waste of my time

Quite contradictory of the title,
*tries to learn how to use matrices to solve a circuit* *finds video called "Use matrices to solve electrical circuits"* *video doesnt use matrices*
great explanation, completely understand the physics and math behind it, really thank you
I hate to be that guy, but if I5 = I6 + I3 then 1 = I6 + 0.5 --> I6 = 0.5
But also I2 + I6 = I1 then 0.5 + I6 = 2 --> I6 = 1.5

Thanks for quick response. Awesome, that would be great :)
Anyways, for now have a nice day :)

Maybe if we used a matrix we could double check it that way!
Wouldn't it just be simpler to have I_5 * 20 = 20?
What if 2 sources have different voltage?
Show me your exact question...
you didnt use matrices you should be honest and say you didn't know how other than choosing a problem you can solve without matrices and I think you messed up a few of your equations
Excellent very clear

Apologies, we've completely stopped that since 2018
