I really love this tutorial, very simple to follow. I hope there a part 2 video about this, which problem solving to test what we have learn and also to improve deeper understanding. Thank you.
Hi everyone! Hope this video was helpful. The written tutorial has a few more examples and goes into a little more depth if you're interested, particularly the supermesh concept: www.circuitbread.com/tutorials/how-to-solve-complicated-circuits-with-kirchhoffs-voltage-law-kvl In regards to the matrix calculator, check out this tutorial - it will be very helpful: www.circuitbread.com/tutorials/math-for-basic-circuits Have a great day!
Hi i really enjoy your videos its insightful and easy to understand and ive watched a ton of tutorials but most just brush over the details, one thing id like you to add thou is a practical example too i mean theory is good and all but in a perfect world the theory wont be so exact and a practical example gets people excited to put what they learnt to the test and feel good when it works out also gives them a chance to get use to trial and error and learn from that as well 3 birds 1 stone kinda... side note only thing that bugged me about this video was you wrote: "10 - I1 * R1 - I1 - R1 = 0" Im sure you ment to * instead of - "10 - I1 * R1 - I1 * R1 = 0" other then that great video and math adds up on my side so i did learn :)
Hi! In general, I think this video would help a LOT: ua-cam.com/video/C8HxYdorsMs/v-deo.html But basically, if you setup the equations for the circuits, instead of solving for each unknown by hand, you can put it in a calculator and it will solve it for you. I highly recommend you watch that video - enough that I'm going to add it to the pinned comment, as it will make this make more sense and make future problems easier to solve.
Great videos. I'm surprised you don't make them on a breadboard or with wires or something as well to measure it and make sure that the math works. After all, circuits are real things!
Y'know, that was originally my intent - to go through the math and then show the circuit in real life, showing how they match. I have no idea why I didn't end up doing that. Now I'm kinda disappointed. 🙁 I'll try and do it with the rest of the circuits videos.
Is it possible that you switched up i1 and i2 at the end? Because I get the same results but with i1 and i2 switched, and wouldn't the current flowing through the smaller resistor (R1) be greater? Maybe I'm just confused, but I even checked with a simulation. Anyway, I really love these tutorials! Thank you so much! EDIT: Whoops, it's explained later.
@@CircuitBread Oh no! I'm sorry! I watched all, but probably wasn't paying attention while I was tying to figure out what was going on on my end. My bad!
I put it into a matrix calculator, like discussed in this tutorial and got those values as the output: www.circuitbread.com/tutorials/math-for-basic-circuits
Before worrying about the math, I would double-check the setup to make sure you put it together correctly. If you have a zero somewhere, that is still part of the matrix. Or make sure you have put the equations together while referencing the correct variables. It would be easier to see what's going on if you jump on to our Discord channel and can show what you're up to. Unfortunately, I haven't been responsive here or on Discord for almost two weeks now because I've been wiring my house (almost done!) but there are a lot of good people that will hopefully be able to help out there.
if your final answers are a negative number i believe you just have to change i whatever go the other way changing polarity and redo it. then again if all you care about is the answer despite polarity...you could.....
Hi Buddy, Thanks for the video. Would you be able to point me in the right direction with the matrix calculation? I just mean how to punch it in to the calculator! I have a scientific Casio calculator with matrix functions.
Actually it's OK I figured it out. Go into Equation Function > Simultaneous Equation and then select 2 Unknowns and put them in as per video. What confused me is that my calculator has a totally separate mode/function called 'matrix'. Thanks again for this great video!
Hey Martin - I'm glad you figured it out! We actually shot a video of how to do the matrix calculation but 1) we use our simplified matrix calculator on CircuitBread.com as an example as it's easier to do than using my TI-89 (never used a Casio, myself) and 2) it hasn't been edited and published yet anyway.
It's a way to represent a circuit with coefficients and put them into a matrix (like linear algebra) and then the math simplifies. I did a tutorial on it here: www.circuitbread.com/tutorials/math-for-basic-circuits but I actually have a friend who teaches math and we're talking about having him do some engineering math tutorials for us in exchange for me helping him with some house renovation projects. He'd probably do a much better job with it than I would!
At this moment, they're probably looking for people in the power electronics side (for their drivetrain) and the controls side (for their Autopilot software). So any practical experience on either of those topics would most likely be a key differentiator for you.
Too many distractions and pauses on the train of thought that makes this exercise effectiveness of around 20%, need to rehearse more on the train of thought !... Forget the logic notation and simplify with real numbers instead so you don't trip on logic, just use plain words, Voltage, Current and resistance, drop the R , I, & V plus # of components....
Thanks for the feedback! We're having some internal discussions on the best way to improve the quality of these videos at the moment and these specific issues are being addressed (and hopefully will be improved).

side note only thing that bugged me about this video was you wrote:
"10 - I1 * R1 - I1 - R1 = 0"
Im sure you ment to * instead of -
"10 - I1 * R1 - I1 * R1 = 0"
other then that great video and math adds up on my side so i did learn :)
Great lecture on KVL. The ending shows the importance of sanity checks!
Yeah, an unintentional example that ended up working out quite nicely. Thanks for the feedback!
great videos, thank you!
I always appreciate the video chapters, thanks
Glad to hear that!
I totally lost it where you put it in matrix calculator. where did -3 7 and 360 came from?

I can't wait for the next video.
what a great channel I found :heart:
Beautiful work over there
thank you , that you clearify a lot of doubt
Great videos.

EDIT: Whoops, it's explained later.
How far into the tutorial did you get? Because at the 20:30 mark, doing the sanity check, I realized I did label i1 and i2 wrong, they were swapped. 😬
@@CircuitBread Oh no! I'm sorry! I watched all, but probably wasn't paying attention while I was tying to figure out what was going on on my end. My bad!
Thanx Sir....
By The Way Do You Have Any Brother/Sister/Friend Who Can Teach Mathematics Or Chemistry Like This 😊
How you get -3/310 and 7/310?
I put it into a matrix calculator, like discussed in this tutorial and got those values as the output: www.circuitbread.com/tutorials/math-for-basic-circuits
quick question i made my own little mesh problem to solve but ended up with a non square matrix... how can i get the inverse on that?

What is a Matrix calculator?

Was the i3 = i1 - i2?
That is correct!

Plz tell me what tesla looks when they need an electrical engineer
