How ur writing kcl formula I3-I1-I2

[@gladys5753]

Studying online,I didn't understand how my lecturer went about nodal analysis and here I am, understanding, thank you so much

[@ikennaokosieme2081]

i do not come to teach but guide you

[@basselh418]

my teacher literally speaks and explains so fast and expects everyone to just get everything he said especially we were in the first week of engineering

[@yvindnordb3855]

Felt that

[@Mikebigmike94]

Thank you! Im reading through a circuit analysis book and its difficult to stay focused, not the most exciting read but its fundamental stuff to be able to learn more interesting topics. I am glad videos like this exist it saves a bunch of reading!

[@arkantrust]

Your video is great and straightforward. Explaining it from KCL really helped me understand it. Thanks🙏

[@SalaheddineJaouhar-v6c]

thank u sooo mu ch i've been watching the same thing for hours in turkish i was feeling like it's a punishement, but u explained it in such a nice and simple way, thank u again

[@alifamran6165]

I've been looking solution if there are 3 fractions for hours now and i'm glad i found this video! i'm so dumb at math and thank you for saving my life

[@samirbhandari92]

Same here

[@zim_al_ghul1397]

xDD same, I was able to solve harder circuits containg more nodes, but here with only one node and 3 fractions, my brain gone brrrrr.

[@clovischefor6869]

We actually solved this exercise in class but I didn't understand, now I get it all,thanks

[@beatsme670]

For real, thank you so much! I like how you make hard topics easier to understand :D

[@Engineer4Free]

Thanks for watching! Glad I can help ☺️

[@leechilton7684]

this video was the first video that actually made sense to me. i love you

[@SnowFlake-hn5ql]

Really thank you I didn't understand what teacher taught u made it clear

[@Samm-z9g]

Wow it was easy explanation to understand.thank you sir alot of love from India ❤️

[@Engineer4Free]

Glad you liked it! I was in India last year, which state are you from?

[@adarshshreshth9614]

Thnx man literally i saw lots of video of nodal analysis but couldn't understand that much

[@immyt8696]

This z awesome.thanks very.much our lectures just rush up

[@Engineer4Free]

Glad I could help!! =)

[@EMFObserver]

This video was awesome! Thank you for the lesson.

[@Awpsun]

Great explanation man

[@harichandandasramanathan2753]

My test is today afternoon and I couldn't understand it from the notes but this video helped me alott thanks man

[@guillaume6373]

Great video, thanks

[@Engineer4Free]

Glad you liked it!! =)

[@DamienAddy-j6c]

Very good video. I really understood it, thanks a lot.🙏🙏💯💯

[@GenesisZeroTechnology]

Beautifully explained. Thank you

[@zudoka1772]

8 min explains better than a week lesson

[@hugo112max]

You were in the Netherlands while making this video right? I could hear it by the ambulance siren in the background noise at 3:56

[@Engineer4Free]

Lol wowwww, good detective work! I did record this one in the Netherlands 😂😂. I can barely even hear the siren on my headphones, let alone identify which country it's from. So good job haha 👏😁. I've actually recorded these videos in many countries, and trying to hide the background sounds is always a challenge! There are some exotic sounds throughout many of my videos 🤣

[@GorenGuang]

@@Engineer4Free I have a question, don't you add currents entering node and subtract currents leaving node?

[@ren5124]

What if the polarity of the 2V source was switched? Like the negative sign at the top and the postive sign at the bottom.

[@revanthkolla]

assume the current to be in the opposite direction

[@mnweeperNancy]

Btw, luv ur voice 😍

[@شاديار]

Thanks for the beautiful explanation

[@southmoreconlin3757]

Thanks, cleared things up for me fast.

[@ashfaquehussain2716]

Nice Explanation

[@Engineer4Free]

Thanks bro

[@celeb1714]

Thank you soo muchh!! This is the simplest explanation for me so far

[@Engineer4Free]

Glad it helped!!! =)

[@eggxecution]

very clear I like this and this is the video where I finally understand how to set resistor polarity lol

[@mallikarjunan8024]

Nice and simple video

[@dutonic]

This is great, thanks so much dude

[@akshithraj9584]

neatly explained

[@denamcmillan1482]

This was awesome! Thank you!

[@KomalaKomala-p4b]

Thank you so much ❤️

[@marthaobagillian9754]

Thanks this is helpful

[@Engineer4Free]

Glad to hear it! =)

[@brayanhernandez1876]

TYSM this really helped !

[@mannyjacobo8499]

Thanks for giving me hope 🙏

[@Engineer4Free]

You can do it!! I have many more circuits videos here: engineer4free.com/circuits =)

[@michaelmyers3507]

Question if there were parallel branches from Va to the 3 volt source with resistors would i just take Req or make more currents for the nodal equation ?

[@user-rt6ij3rz5y]

You are a legend

[@Abdullah_klx]

عالجد يارجولة 💖💖

[@ADITIS-ss5ne]

Can u suggest any book where I can solve more questions on this topic?

[@geocors6139]

thumbs up finally understood the topic

[@sulimantbg5936]

why on the I3 you put the number before the V but in I2 & I1 you put the V after??????

[@AKgarbagemonkey]

Is there a video for nodal analysis with 2 currents and 2 nodes

[@yosefpatinio3669]

it is possible to do nodal analysis for a voltage and resistor only? (one loop only)

[@HarshYadav2004]

Tysm:)

[@Engineer4Free]

You're welcome, thx for watching!

[@СанжарАлманов-т3с]

thank you!

[@benitezdenmarkvincentr.3526]

itis truly helpful

[@siddharthpg2919]

thank you so much !!

[@kairavb]

Thankyou friend :)

[@cjesguerra5575]

how did u get the 1.143v?

[@CORExisnthere]

dividing by 7 on both sides, so 7Va/7=8/7 basically Va =8/7 that is 1.143 v

[@universeexpansion9982]

great

[@Engineer4Free]

thx

[@mdjonimia3569]

Thank you so much

[@redroses4679]

Hi how do you find Va

[@Engineer4Free]

Hi yeah its shown in the video

[@safayiakako3416]

Good!

[@DrakeDamron]

wow, thank you

[@ii3.4zz]

i dont get v3// why not (1-1.43)

[@dankbank986]

you got an answer yet?

[@no_melon]

What if I get a negative V2? What does that mean?

[@CORExisnthere]

it means the polarity you assume is opposite of actual polarity, its stilla correct answer (correct me if im wrong)

[@shahdeddahane4090]

thank you

[@robertleechford4250]

Great

[@Aryan-dc8kr]

4:26 Sir shouldn't we do Vfinal-Vinitial😢,plz help sir

[@CORExisnthere]

not nececary its because we assumed the Va to be smaller than 3v so we always subtract smaller from greater (correct me if im wrong)

[@anastarafder2637]

why did u plus the Va at 6:02

[@user-er9zm2no4g]

when (-)(-), its become (+)

[@Mo.sameh2023]

ممتاز 👍🏻

[@Seraphim316]

Why did he divide it all to number 4?

[@ShehabChowdhury-ng5ug]

Lcm

[@karnez05]

So your not solving for current?

[@zarithevill]

gotta use KVL instead if you're solving for the current

[@yesicarobles8122]

Why are you multiplying by 4 at 4:53?

[@teamo8033]

Just to make the equation neater by removing the denominators. He multiplied both sides of the equal sign by 4, so the equation communicates the same information as it did before the multiplication. On the right side of the equal sign, 4*0=0.

[@Seraphim316]

HOW DID IT BECOME 7VA =8

[@b21martosvhenzkirbym.29]

He add the Va together as well as the -6 and - 2 together. Then after that he take the -8 which is the result of -6 and -2 to the other side which made it positive.

At 3:26 why did you say the moment is anticlockwise when it's being rotated clockwise kzbin.info/www/bejne/qZ7SgZ-AnrGgl8U

[@Engineer4Free]

Counter clockwise is the positive sense for moments. F1 alone would cause the wrench to rotate clockwise about A, same with F2, and F4. All forces individually would cause a clockwise rotation. Notice how the moment caused by each force is a negative value? It just means that it's a moment with ___ magnitude, and the negative sign means it's going opposite the positive convention. A positive moment would mean the force tends to cause a counter clockwise rotation, but these are all negatives, and they all have the tendency to cause clockwise rotations, so hence their sign is negative. Hope that helps clear it up.

[@krisnastha3938]

Really appreciate your work. 👍 But the figure has ony two nodes not five.

[@madday9589]

Actually it has 4 nodes, one he made grounded

Sorry, try setting the speed to 0.5x maybe! Good luck 🙏

[@jkcnewstoday]

redo this

[@gouravrao564]

Bro at least speak clearly 👎

[@ray67686]

u sound like a pilot man get a better mic

[@SXZLegionary]

I have a question. Why did you multiply everything by 4? I am looking through my class notes and on one of the examples they multiplied everything by 60 and another example by 120. I'm struggling to understand where those numbers came from.

[@beet311]

well you just multiply by whatever number to get rid of the fraction, in this case we get 4 from the denominator

[@beet311]

also whenever an equation is equal to zero we can multiply it and divide it by any number we want (except for 0)^

[@SXZLegionary]

Thanks!
