10 - Intro to Mesh Current Circuit Analysis (EE Circuits)

View more lessons from this course at www.MathTutorDV....
In this lesson, the student will learn about the mesh current method of circuit analysis. In this method, the circuit is broken into several meshes where a current inside of each mesh is assigned. We then write a system of linear equations that describe the entire circuit in terms of these mesh currents.
Once the mesh currents are found, any other voltages or currents in the circuit can be easily calculated. This is a central method of circuit theory and is used for many circuits where the node voltage method is cumbersome to use.

41.5 mins with your instructions are much better than a week asking my professor and him not even wanting to explain!

[@MathAndScience]

Thank you!

[@victorjimenez7213]

8 mins in and wow. I wish my professors taught as well as you do. I’m a Senior ChemE student dying in a basic ECE class. Bless you sir

[@justasydefix6251]

Just so you know. ChemE has some relationships with EE. There are Batteries, computerchips etc... Unless you narrow your chemE to bio or something like that but then you will still have to study EE physics.

[@josephh.3896]

This guy is incredibly good to explain complicated things simple. Thank you Jason the Professeur

[@MathAndScience]

Awww Thank you so much! - Jason

[@ALEX-gr7dx]

I've used a lot of youtube tutorials youre the best teacher whether its engineering circuits or Laplace transform or any topic for that matter.

[@LORDzFX]

I’m very grateful sir
You saved my exams 🙏
God bless you

[@aaronstaana]

This saved my butt studying mesh analysis during this online classes

[@proxy8918]

Thank you so much. I didn't understand this at all until watching this video. You are an excellent teacher.

[@Windblade66666]

I really appreciate this video by a lot specially the part when you explain the polarity of the components in mesh analysis because for a very long time I was mixing then up with KVL and it made so confused for a long time. Thank you very much and I hope for pleasant event for you all the time

[@NEEVURIVENUGOPALREDDY]

one of the best lecture i've ever seen thank u sir

[@IamPhant0m]

I’ve been struggling in a mining circuits class and this has helped out a ton!

[@pranathidevulapally9418]

This is actually a model of my homework Problem... it's really helped me...🙏👍

[@Ajalgai]

You are good teacher who knows how make student understandable

[@TheRandomShow52]

Thank you so much! My electronics tutor has no real understanding of this topic so its good to find a lesson taught so clearly

[@rods6405]

Thanks very much for this. It helped me confirm Hafler circuit operation for audio that I had worked out in Excel using just ohms law.
Basically the same CCT but, AC generators not DC, and 2Ω and 4Ω res are 0Ω and others are 8Ω(speakers)
I did electronic engineering 40 year ago!
I then used your matrix method and also discovered that Excel has built in inverse and matrix solving features,
I was so happy when I got the same answers.

[@yusdobhipakage2128]

Thanks for the explanation of the formulas which I felt the most and did not know before and now I can understand through his professional explanation. Great sir.

[@opiasareginabea9869]

Thank you Sir ! You explained it very well. Now I have understand how to use the passive sign convention. Once again, thank you! May God bless you more!

[@MathAndScience]

You are most welcome

[@jeffjefferson2676]

Pretty good explanation. It helped me out a lot with my homework.

[@neil3858]

Exactly what they teach in Naval A School. Great material.

[@drproton85]

You saved me in class! Thank you so much!

[@johnkyingilisi4395]

I used KVL and achieved the exact 28.8v ,in less than 10 mins.However in front of camera while explaining it to students it is a lot more difficult. Excellent tutorial.

[@MathAndScience]

Thanks so much!

[@gloriaFometio-s9b]

Wow this professor has so many experience

[@TheElectromagno]

Very well explained with a fantastic pedagogy. Thank you very much.

[@udoemmanuel983]

Thanks from Tanzania

[@abdullahshakir7401]

Why do I even go to college....

[@anthonyasabere1364]

Yes man.. What they take 3 hours to teach us we don't get it.. When we come here for 40 mins, we get it better

[@WeLit999]

😂😂

[@BeekersSqueakers]

Because hiring managers are lazy.

[@mohamedehab1255]

so BEAUTIFUL ! awesome content, thanks ^^

[@ndoewsithole8555]

thank you sir I almost went to write my exam without getting this right.
thank you

[@naderhumood1199]

Thank you v much Sir. Great lesson.

[@vakhariyajay2224]

Thank you very much. You are a genius.

[@MathAndScience]

Thanks so much!

[@kiellandbrwn1]

This man is so cold 😮!! You dont truly understand something if you cant make it simple and my teacher doesn’t truly understand this

[@brianramz6681]

i just hope on ur videos you have thevinin and supersposition technique... thanks for ur help

[@lawrencejohnson5537]

He killed it absolutely

[@cesaru3619]

Professor cheeks is the BEST!

[@satyananda4389]

Thank You So Much Sir Jason

[@jaappoldervaart7851]

Thank you, your’e a super teacher, it’s cristal clear!

[@zachp2389]

Jaap Poldervaart how did you make it all the way to engineering circuits without knowing how to spell?

[@bilkisakther6277]

At Mesh C :will it be (-20) or (20) in the 1st line as it is going to (+) to (-)..
pls tell me....

[@zilog1]

interesting that we act like a current is going in one way and the math still works out even tho its not the way current is flowing at all. very interesting

[@rameshkumarthayyil]

The explanations make everthing really simple. Tkank you very much sir . but can we solve the same with Node Votage method?

[@tresajessygeorge210]

THANK YOU... SIR...!!!

[@MrWindow789456]

Thank you, next time can you show us how to do EE Circuits matrix with a calculator? I got it anyway. But that will be easier for those who doesn't know matrix.

[@rhecavillaceran5564]

Thank you Sir!

[@michelvandenakker4875]

It is so much easier if you just apply the superposition principles using the Thevenin and Norton equivalents of voltage and current sources. You can almost do it without a calculator. No matrix calculations required!

[@rods6405]

That's what I thought off the top of my head but could not remember what it was called then I looked up superposition and bugger me I did this at Tech College 40 years ago.

[@ciphernx]

i probably made a mistake somewhere in my homework and will get 0 for a specific question because this is electricity but still thanks for the video, helped very well

[@shreetuljabhavanimandirkal1787]

Thank u so much sir it helped me a lot

[@brianrosado7211]

This really helped.

[@Formidable_foe.]

You sir are amazing🔥🔥🔥🔥🔥🔥

[@CoffeeeTea5849vfvf]

You are amazing . Thank you

[@geraldmuhumuza4017]

I like this sir.
Thnx

[@MathAndScience]

Most welcome

[@incudust953]

at the 11:30 mark u state that + to - is positive and - to + is negative, but it doesnt matter how u use the sign convention. so do u mean i can write in + to - as negative, and a - to + as positive and it wouldnt matter as long as i follow the same sign convention around the whole circuit? Im reading schaums basic electricity 2nd edition and it states that + to - is negative, and - to + is positive.

[@alias6676]

man so many people explain those methods in such overcomplicated way. Usually they try to figure out the actual way current flows only to ignore it later

[@5amdrive465]

Thank you

[@shicarter6969]

What video do I need to watch to know how to do matrix Ax=b?

[@jom5955]

I'm confused, I know that resistor consume energy, so whenever a current passes through a resistor, from positive to negative, it's create a drop so the sign is negative (-) but you are saying different things that we should asign positive (+) for the resistor when a current passes through from positive to negative.
Please I need more explanation because you are confusing me

[@Detonat0r]

thank you so much, you are awsome

[@kurdapsbakeks4507]

So fun to watch

[@LaminBMassaquoi]

Thank you sir, but I don't understand the matrix solving skills.

[@brianramz6681]

finally i understand my EEEN201

[@MathAndScience]

Awesome!
Jason, MathAndScience.com

[@elchuginho]

Why not just use rref on the calculator to solve the matrix?

[@STP31]

Thank you soo much sir

[@richardofori1868]

I don't understand why the first equation had -40. Should it be +40 because it there was a current motion from the negative through to the positive

[@keymarktarape1081]

Wish you were my professor my professor is very lazy to teach computations and she just reads the definitions and doesn't explain it

[@lalith_kumar_akhila2411]

Thank you sir

[@nikhildcunha4335]

thank you very much

[@mburupeter7983]

I salute you sir

[@reginaldgarcia1549]

I am confuse for a second there. I was watching a negative voltage drop, i thought i was wrong HAHAHA

[@workoutmusic4236]

Best easy example

[@daksamuel5273]

Wow
Look this guys teaching

[@strangeperson700]

God bless you man! :)

[@MathAndScience]

Welcome!

[@ndereratjijahura2048]

I need examples of nodal analysis for circuits with two voltage sources and five resistors when finding voltage 1 and voltage 2as well as current through each resistor

[@ivancastro365]

shouldn't Ib= 4.75. I got your equation for ib in terms of ic and 20v and I also got ic=0.8

[@nokuphiwamncube5370]

I'm really confused with your calculations sir ... I don't know how you get voltage rise in all your resistors😭😭

[@tomjoad6993]

In this video: watch?v=k5Tlg27JDtc he says when going from - to + you use + because it's a voltage rise. So for the power source you would write 40 instead of -40. Why did he say that? Because what he said makes more sense than what you are saying in terms of going from - to + is treated like a voltage loss since you use - i.e. -40 in this example.

[@m4ck825]

does it matter if your using conventional or electron flow?

[@yushengtzou]

Is ia equal to i? Thank you~

[@emre-cil]

you are king

[@geminilouvre7789]

thanks, Sir, but I have a question. How can you solve the power absorbed by each resistors?

[@lorimaureen5305]

How to do the matrix on sci cal?

[@danial9070]

Wait, mesh current and kirchoff current are different things?

[@rakibhasan7950]

thanks a lot....

[@harisuwr]

thank you so specificc

[@adamcryer5990]

How did he get the decimal values at 30:12?

[@ivancastro365]

How come you can't keep for mesh 2 +R2(ib-ia) and for mesh 1 - R2(ib-ia)? *I'm keeping voltage drops from - to + positive and + to - negative. PLEASE HELP test on tuesday

[@shahlaanjum9080]

I have the same query

[@russelgeraldpenaflor8683]

Sir how about theres a capacitor and inductor in circuits?

[@Isaac_blingz]

exactly my question

[@oduroflames3349]

Solving the equations simultaneously gives wrong answers..
Can someone tell me why

[@nhitc6832]

you probably made a math error somewhere.

[@jv_lamsen10]

I think the indication of the "plus" and "minus" sign are wrong... if I'm wrong please explain it to me. Much appreciate it.

[@anushapalepu9633]

i felt the same..and i am still confused.
