I was having so much trouble setting up the equation at the current source inside the super mesh. Didnt know which current to subtract from which. Thank you so much for clearing it up for me! You're amazing
My professor said i will not give you any examples that the current source cant be converted to voltage source *XD* but i love circuit in general that's why i'm here *:D*
When you have taken voltage 24V from voltage source for the first equation, and in the second equation how can you take current source value to simplify without converting into the voltage?? please reply me. Thanks in Advance.
Shouldn't the voltage on the 40 ohm resistor be (40 ohm)/(i1-i2)? considering we assumed a downward polarity, the equation for that voltage should be the same for both meshes.
Mesh analysis is different to nodal, we work not with accrual current but with mesh currents where we assigned a clockwise direction. So when you write mesh equations, you pretty much don’t worry about actual current, just take mesh current as a positive direction and so you need to subtract the mesh current flowing in opposite direction to the primary mesh current.
With regard to the supermesh, why did you combine the opposing currents i2 and i1 at the 40 ohm resistor, but did not combine currents at the 20 ohm resistor with i2 +i3?
If you havent gotten your question answered already, one thing that isnt the clearest is she has currents i1 and i2 that need to be found, yet she calls the mesh currents she created I1, I2, and I3, it makes it confusing and harder to understand, especially since she wrote lower case i's in her equations when she was talking about the uppercase I's to answer your question now, She combined the opposing currents I1 and I2, at the 40 ohm resistor, she didnt combine the i1 and I2. Thats why she didnt combine i2 and I3 at the 20 ohm because the i2 isnt apart of finding the mesh current, its going to be a value she finds from her mesh currents, which in this case i2 = I3
Mam I have one doubt in voltage source we take (-to+) the voltage will become +ve voltage y u write in -ve......and in resistance (-to+) the resistance comes -ve sign comes Please tell it
You can choose if -to+ is +ve or -ve , same thing with current leaving/entering a node. But once you choose, you have to use that same way for the whole circuit. You get the same answers.
They're are many ways to solve for the circuit, I actual solved it before she did using superposition, but in this case it would be extremely difficult to use Thevenin-Nortons theorem
because if you look at the diagram you will see that we want to find the value of I2 and at the same time the current passing through the 3rd mash resistor doesnt share with any other mash, so it makes the value of i3=l2

Its 1hr before the exam and I finally got this! Cheers gorgeous! (I'm off to nail this!)
2 hour before exam here lol.
Thanks from iraq🇮🇶
I loved your lecture ❤️
Thank you! Your explanations are much easier to follow than my professor's.
Very HELPFUL indeed.😊 Do watch it everyone who is in need to understand mesh and supermesh properly!!!
Most straightforward method so far. Thanks
I have a quiz tomorrow, now I feel much better thank you!
شرح رائع شكرا لك من هندسه الزقازيق في مصر
♥️♥️♥️
i wish u were my basic electrical teacher..thanks a lot i knew many new concepts here thank u very much
Спасибо вам большое, очень просто и понятно объясняете ! По больше бы таких видео.
you are really good at what your doing😀....thank you !!
Its actually a pretty good video to explain mesh analysis thanks!
I keep zoning out because your voice is so soothing
this video was extremely useful! I did not think of the i2 + 5 = i3 part until i watched this. Thank you very much!!!
Very informative. Thank you!
Thanks LOT ... !!! It was very Helpful for me .. Thanks a lot, you are far better than my professor :D

hunar omer تۆش کوردی گیر خواردوە بە دەست پڕۆ تەڕەماشەکەتۆ 😂
Very well said
Phenomenal explanation, thank you Marina.
thanks 4 such a good example.
Thank you Very Much! its helpful today will be my exam 🌹🌹
MUCHISIMAS GRACIAS!!!! SALUDOS DE SAN DIEGO CALIFORNIA :D
thanks a lot,you have explained very well..
Thanks a lot I really thankful to you you taught me in easier way
Very helpful ......thanks from egypt
madam -excellent -thank u -
marina belkina .............. i wish you a best job
Thank you sincerely.
thanks a lot for the great explanation! it is very helpful!
Thanks alot you are so great
thank you.. :) u helped me pass my exam
Extremely helpful!!!!
Really god blessed you ♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️ than you very much
thank you marina....helped me a lot
U r voice is super
useful tutorial ..........helps to learn fast
Thanks
God bless you
nice video, ggwp
really help my study in basic electro
Thank u so much....this is really helpful..
Thank you so much!! You saved me! 💘
very useful video..... good work
i am getting the exact same values with exactly opposite signs with the same direction of mesh currents you have assumed
Thxxxx prof. 💚💚
Really helpful!
Thank you so much for making this video. SUPER helpful!
Thank you, you helped a lot
thank you so much marina
good lecture... too helpful
Gracias por la explicación.
Si me caso con alguien como tú que sepa analisis de mallas.
should define simplification
thanks a lot... really a helpful video to understand this concept
send me a friend request
Armaan Butt who are you?
I am Phenomenol..........
#Talklessdomore.
thanks a lot... this was great
Thanks, very helpful :)
Thanks lot.. U r far better than my iit professor...
Thank you very much! :))
棒棒哒
Big up yourself ....... x2 :)
Simple and Easy
very good
God bless your soul
Excellent madam 😀
thank you
great !
According to my book when you have a negative sign first you add that voltage not subtract it.
Thanks
شكرا
I tried solving via CCW mesh currents but I can't seem to get the same answer. The third equation would always be equal to I2+5=I1
Wow mam
When you have taken voltage 24V from voltage source for the first equation, and in the second equation how can you take current source value to simplify without converting into the voltage?? please reply me. Thanks in Advance.

+Marina Belkina ya... My teacher explained me same thing..
great!

I get it ya amarr 🥰🥰🥰
super thanks
With regard to the supermesh, why did you combine the opposing currents i2 and i1 at the 40 ohm resistor, but did not combine currents at the 20 ohm resistor with i2 +i3?
If you havent gotten your question answered already, one thing that isnt the clearest is she has currents i1 and i2 that need to be found, yet she calls the mesh currents she created I1, I2, and I3, it makes it confusing and harder to understand, especially since she wrote lower case i's in her equations when she was talking about the uppercase I's to answer your question now, She combined the opposing currents I1 and I2, at the 40 ohm resistor, she didnt combine the i1 and I2. Thats why she didnt combine i2 and I3 at the 20 ohm because the i2 isnt apart of finding the mesh current, its going to be a value she finds from her mesh currents, which in this case i2 = I3
I like you thanks
Your voice ❤
my math isnt that good how did she reduce mesh1 and supermesh
but its seem both I1 AND I2 going clockwise according to arrow i am confuse can you help? :)
what will be ta power delivered by 5A source?
love you
Why not just use matrices?
7:59 I got 1I2 instead of 11I2 i think you made a mistake in adding and subtracting
Hey Jean see this video to learn the technique

Your ans is wrong , mam(i1=-0.82, i2=-1.62, i3=3.37)
but will happen if there is a resistance in series with the current source
+abdelrahman esmat It will then be a voltage source! :P
It will simply be another mesh
Why do we even need supermesh here? Since there is the current source parallel to (30and 20) we could just Thevenise couldn't we?
They're are many ways to solve for the circuit, I actual solved it before she did using superposition, but in this case it would be extremely difficult to use Thevenin-Nortons theorem

Thanks a lot can I call you over the watts app I live in North America.
I need to ask you a few question
Accept but why i2=i3 ???
because if you look at the diagram you will see that we want to find the value of I2 and at the same time the current passing through the 3rd mash resistor doesnt share with any other mash, so it makes the value of i3=l2
its Clock wise you perverts!!! anyway Thanks a lot

Can you translate into Arabic , please .
Russian XD
you should have shown how you did your simplication totally useless
अरे भाई! Pair of linear equations हल करना नहीं जानते क्या???
I mean to say don't you know how to solve pair of linear equations huh!..
Thanks
