This video aged 10yrs, but I'm using it today!! Thank you so much!!

[@WestVision]

your a very good teacher. I love how you always review everything you do after a few steps. Im struggling a little in class to keep up because we just keep continuing through the problems with little to no review.

Sir you are great in such a small period of time yo bring much clarity keep it up, its people like you who inspire us to be lectures

[@anwarhussain5875]

Great teacher, easy to understand his accent. great explanation. one my fav teacher

[@grantstidham9322]

FINALLLY, A USEFUL EXAMPLE So many of the examples online are so simple that they do not hit very important small details about the mesh current method, so that you really only know how to apply it for single-loop circuits

[@RafiqUlIslam-ej2eu]

Thankyou so much sir.... You way of teaching is much more better then the people staggering for publicity on youtube

[@NneomaEzirim]

I'm grateful this video is still of help to me after 12years

[@MathAndScience]

Hi, to calculate the matrix inverse is a fairly involved process. The inverse in this problem is correct. I recommend that you study up on how to invert matrices. I have many tutorials on that!

[@denvercharlebois699]

If I was to choose kvl would it be a lot more equations then the mesh current?

[@orlandomcallister]

I sincerely hope that students take full advantage of your lessons to enhance their learning in engineering programs throughout the world.

[@aliakay8568]

you are amazing teacher.do you know that you saved a life ?? :D

[@slabjr2]

Great Video! The only thing I would suggest is showing more detail on how to solve the matrix without a calculator. Can't leave out Crammers Rule.

you have no idea how useful this was. beautiful man!!

You, sir, are a gentleman and a scholar. :) Thanks for such a classy and clear explanation!

[@tnekkc]

U of WA, EE dept 1975, we had to learn this by reading a book. In all my years of designing power supplies, I never used mesh equations once.

[@kaycortez1]

your way better than my teacher, finally understood it

[@Flintsmooth]

I noticed that circuit is actually a bridge, with the 10 ohm resistor as the center. I've been trying to analyze a bridge with no luck, (I think I'm making errors), anyway I applied thevenins theorem to the center resistor and came up with 45.8v th and 13 ohms th and it all worked out! Thanks a bunch!

[@angenclinton2276]

Sir your lecture is making me thinking different I really like the way you teach

Thank for given me a good understanding of how to solve mesh circuits problems.

[@budhabiya1232]

Nice explaination thx, but im wondering about 100 voltage why its negative while its rise !!! Should be plus i think. Thank u very much.

[@RoyAndrada]

Budhabiya maybe the following is the reason why the two opposite conventions are popularly used. Some follow the logic that for every voltage rise is a plus, and a drop for every resistor (because that's what it really is) is a minus. However, if you will follow the passive sign convention of power in a circuit (supplying components are minuses and absorbing components are pluses) then the sign convention changes. We can use whichever sign convention we want as long as we stick to it within a solution. thanks for the video

[@240mains]

some people write the KVL sign as they Enter each component . Thus , -neg terminal is Entered and we write - 100 . Of course some people might write the sign as they Exit each component , in that case , we would write + 100 v . This is NOT confusing nor double talk . read chapter 1 and 2 of book : ISBN : 0-07-027410-X Engineering Circuit Analysis Fifth Edition , 1993 . Note : ALL 2 Year Tech School books have insufficient info to properly write equations . ( High School teachers don't know how to do it either ) As I was saying in my original Stand-alone-Post , he Never talked about How he Wrote the Equations . That should have been the Whole Point of this tutorial , but he did NOT do that . Hence your question . If you are coming from Electron Flow , then give that up . Because all the 4 year books use hole Flow . If you want to write equations , you will be using hole flow . If you want to use Pspice , you will be using hole flow . read chapters 1 and 2 of the book above . That should fill in ALL the gaps in DC circuit equation writing . You MUST read a Four Year book , such as mentioned above .

[@venkat4137]

He should use positive sign for volti

[@maselynkopuria5882]

Thanks very much for your explainantion.Now i have confident in my upcoming exam.You really a great teacher

[@ekc133]

Good solving technique of solving mesh by matrix... Thanks for your method sir.. It made solving very easy.

[@sagar9703]

Wow what an incredible explanation . Tq sir helped more than my professor's explanation.

[@lifeatmemes]

top notch video. true excellence. you touch on subtleties with convention esp. with the voltage drop from negative terminal to positive as negative, and assuming the polarity of the resistor to conform with the direction of current being analysed at that point. keep it up!

[@ณัฐวัตรจอวัน]

Thank you,that's great teaching. That's so good for me.

[@240mains]

I think he missed it . No Passive Sign Convention . and he plugged the coefficients into a matrix to solve the system of Eqs( beginners never use a matrix ) , while he wrote all 3 initial equations the "hard way" . all that will definitely confuse any beginner .o'well . Edit Dec 29 , 2018 read chapter 1 and Chapter 2 of book : ISBN : 0-07-027410-X McGraw-Hill Engineering Circuit Analysis Fifth Edition 1993 . Chapter 2 covers the Context of Mesh analysis verses using basic branch currents . Look on page 65 66 67 Yes , this book does NOT talk about writing equations directly into Pattern Format . ( NOT sure why Pattern formats are NOT included , cause the book does plug into Matrix's too , and the equation format that plugs into the Matrix is the Pattern , which can be written Directly by Inspection of the circuit diagram ,...too easy . The Final form Pattern of each equation is there , but the authors never mention it )

very clear explanation. Thank you very much. I have a doubt. Why are we considering current in a clock_wise direction?

[@manojmaharaj1775]

Santhi siva You can take in any direction. We are just assuming it. You can use anti clockwise direction and still arrive at the same answer

[@240mains]

@@manojmaharaj1775 again , ( kind of ) , the same answers . CW clock wise arrow might give an answer of -2 amps , while if we had use CCW counter clock wise arrow , we would have gotten an answer of + 2 amps . Both answers are ( Valid and Correct ) . do you know why Both answers are Valid ? ,...i know why .

In the 2nd equation which is ib why we didn’t add -100V to it???

[@EmanoelGjata]

Bro is doing the work of GOD

[@z-rak1051]

Hey, what would you do if there was another voltage source as well as the 100v source. (particularly at the matrix step)

[@knightshavealot5943]

quick question: can I take the I (sub b) mesh to start at the 100V source then into the 20 ohm, then through the 15 ohm, and back to the voltage source? It's a different loop but it still covers all the resistors. Thanks!

[@Luke-qc1rm]

no, because there are resistors in the middle of the "super mesh" you propose. the current changes when it goes into other branches (KCL, conservation of charge), which is essentially what you would be ignoring by creating that super mesh.

[@knightshavealot5943]

Luke Porter Thanks a lot for your answer. Very clearly explained. :)

You are very welcome!

[@elijahrainville2500]

Man This helped a lot. Although only if it was that easy to get the inverse, sadly in my course we have to do it by hand and aren't aloud the use of any calculators that have matrix type functions. Although I use Cramer's Rule for the other stuff since I like it more.

[@frankvalenti8350]

this guy is awsome

[@HabiburRahman-xs9gb]

we can also use Cramer's law...instead of the matrix thing...ryt??btw your teaching style was awesome....and helpful
