- Physics Ninja shows you how to setup up Kirchhoff's laws for a multi-loop circuit and solve for the unknown currents. This circuit has multiple voltage sources and cannot be simplified using resistors in parallel and in series.
Holy god, words cannot express how helpful and useful this lecture was. Men and women like you drive humanity forward. I wish you nothing but good luck in the future. God bless you.
why do i bother paying 34k/yr in tuition for a professor that couldnt teach me what you did in 19 minutes? Thank you Physics Ninja
Thanks for watching!

During our times there was no internet and we used to depend on our teacher. We use to go for exam without understanding properly. This generation is very lucky.
Where are you attending that is that much per year? Thats 4 times what I'm paying in tuition at my State University. Thats the full cost of my entire degree.
Unless your going to a world class university, you're getting ripped off.
@@PhysicsNinja Man I did my degree in Engineer now been working as electrician etc but where do we find such things in real life? Can you give an example of such a doubel source DC voltage in a single circuit anywhere? If not then what was the point of learning all this stuff?
This is literally the best physics lecture I’ve gotten in physics so far! Thank you so much!
Thank you so much for the kind words.
@@PhysicsNinja thank you for telling me which my teacher couldn't do in 2fuckin years
After 3 videos on this topic, yours is the one that helped me finally get the hang of the rules. Thanks!
I was struggling with Kirschoff's Law but this really made me realize how simple it is! Thank u mr. ninja appreciate it
i love how enthusiastic you are about this
thanks a ton for making it simpler
I really appreciate this video. I appreciated you breaking things down and explaining very simply from the beginning what we are, you helped me understand how you can "walk" around the loop in one direction and have the current going in a different direction. My grade and more importantly my understanding have been improved as a result of your work. Thank you!
I love you. Seriously. It's amazing how fast things can click when they're explained well. Thank you!
I like the energy and flow in these videos. 💪
My GROOVY Bro... Watching this takes me way...way...way back to high school electronics. They barely had hand-held calculators back then. I barely got through with a "D". I absolutely admire your ability to minipulate those equations I struggled horribly with. The way I'd do it is...set-up the circuit in reality, throw the switch, then jump out the window and wait for whatever battery or resistor blows-up first. (Repeat process 3-times). Increase resistor wattage rating each time.) The Professor.
this channel has been a lifesaver
You have the most engaging teaching voice. It's as if I am at a fighting match but for physics! Love it! :)
Learned KCL & KVL a while back, this served as a great review for me, keep up the great work!
Watched hundreds of videos but this one makes the most sense.
I learned more in this 20 minute vid than my hour long class. Well done
Thank you very much! You've cleared all the questions in my mind regarding this topic.
Good 'circuit sense' explanations combined with KCL/KVL loop analysis to derive a system of three equations in three unknowns (the three loop currents). Also, good follow through on solving system of equations by substitution for elimination of variables. The bedrock of electrical circuit analysis. Mesh analysis techniques can be easily mastered later with matrix algebra used to solve more complex systems -- kudos for your common sense approach, which I think is very helpful for developing a sense of what's going on in the circuit!
literally saved my time, such a simple and detailed explanation! Gottta give this video a like, thank you!!
Thank you so much! I wish I have a professor like you
straightfoward, subscribed.

I feel like I stumbled upon a pot of gold. You're seriously the greatest. Thank you so much.
Happy to help!
Three days stuck on this topic this man shows out like fucking batman and saves the day!
My teacher at school doesn’t know how to teach. You are amazing! Physics ninja to the rescue!
I think we all have the same kind of teachers.
I really understand that video. This video had perfectly clarified some of my doubts. I really love it. Thank you Physics Ninja.
I have all the information from the book but just 😢 can't trust my methods
I'm also grateful I found this video
ten seconds into the video and i love this man already
Just want to say thanks for this great Video. Everything is simplified and very easy to understand.
Thank you
This topic was always super confusing for me, but I finally get it now. Thanks a lot!!!
I also
This concept did not click until I watched this video. Thanks Physics Niinja 😎
What an explanation I didnt understand this thing for a whole term now I know it it turns out to be easy
Very nice explanation bro... Love from an Alevels student of Pakistan 🇵🇰 👌🏻😍❤️
Wow! I can't believe it was that simple. Thank you so much!
Sir, your energy was so good in explaning love from india
I like my professor but I was unable to understand this concept for weeks and in the first five minutes of your video I get what I was doing wrong. Thank you.
School teachers are stupid. they don't teach properly.
I have not yet had a class on these multiloop circuits but I've already understood the concept....thanks to you physics ninja
why are you watching the video then?
Thank you for this explanation !!! Hopefully I will not fail my exam tomorrow !! Fingers crossed !
Bro your algebra skills are on point respect
Dude, Thanks a lot for this awesome explanation!!
For anyone who has taken linear algebra - you can do all the algebra with matrix row reduction! much neater to work through that way
I understand it very well , and
I want to tell u that u have a lot of patience I was so messy with those three equation but not now anyway thanks sir
thank you so much, i literally spend 2 days to figure this out.
Thanks a lot Ninja...This video has helped me a lot....You are doing really good.
This video is just awesome. I like your explaination sir God bless you
thanks a lot sir! a real learning early morning is best!
Amazing video, extremely helpful
Just wanna say: thx a lot. Friday is my final in introduction to physics and Imma give some news next week when I get my grade. But thx I finally able to learn something so simple! It’s quite humiliating but God it feels good!
Best of luck!
thanks, easy explanation didn't even have to finish the whole video
Question regarding resistors being placed horizontally: is the positive side always placed on the right side and the negative always placed on the left side of them?
16:35 i'm kinda confused on this part, why does the value 2 in the equation its in the i1 (the substitute)beside denominator?, and not below the substitute ? (sorry for my bad english)
I FINALLY LEARNED HOW TO DO THIS BECAUSE OF THIS VIDEO THANK YOU ! ! ! ! ! ! ! !
At junction d, how do you know the correct direction of flow of current
Well explained and you deserve thumpsup and subscribed
very helpful. keep doing complex examples
So what happened with the rule if the amps is minus than you have to change current direction?
Beautifully explained. Thank you so much.
Thanks for the help. I was stuck not knowing how to do my lab.
Best video I've watched on this. Thank you
This video is great at explaining this concept.
Thank you sir.u were clear my doubt🙏
That was really really helpful, you're awesome
Fantastic video, thanks for sharing you knowledge
My pleasure!
Great and simple way to teach.
Umm can anyone tell me where the current I2 is coming from cuz I don't see a battery nearby to provide that current
Very clear explanation thanks a lot 😍
You have made me a loyal fan. Great job with the explanation!
Glad to hear it!
You literally saved my day .Thanks
hi! this video was so helpful! I was wondering where the current in the middle of the circuit originates from? Is it from the 10 V battery? Thanks!
It was so so helpful your lesson!!😍🔥🔥🔥
this is video is so underrated!!! i finally understand this, thank you!
yes you are correct
Nice video, well done, thank you for sharing it with us :)
Thanks a lot for explaining very clearly
This was amazing thx you so much !! great lecture :D
i think you may have just actually saved my life
Very clean explanation, loved it!
Thank you so much for that explanation 😊
Amazing, it was a quick and exact explanation of a lengthy method. 🚩🚩🚩🚩🚩
Thank you so much.
Thanks man. You saved the day.👍
it seems like the 20V and 10V batteries would be fighting eachother. does the 20V battery really just overpower the 10V and allow current to flow through the 10V battery backwards?
how we decide how many current we should put
What if the other 2 voltages are also unknown?
After 3 another channel best one was that thanks for everything :D . I believe tomorrow ı ll got ıt that fınal exam.
how did you go!
life saving, thank you!
Now am back on track thank you
i notice a mistake in 11:50 where you transposed the -10 and -2I_1 and the -10's sign stays negative. Isn't it suppose to be a positive now?
Excellent explanation thanks
nice sir, watching your video from Pakistan and your teaching method is very good.
Thank you
Thanks you you helped me passed my semester
Thank you so much for the helpful video
thanks you made simple its easy to understand
This was so confusing for me at first but I finally get it. The one thing I don’t understand though still is why the direction of current doesn’t matter and how would you know if you guessed the wrong way
Love from India 🇮🇳♥️ I'm in final school year and these explanations are helping me a lot
Happy to help! Good luck with your studies.
it will be a pleasure if yuo could made another one of most complicated and hard
Nice and amazing and very simplified video , thanks a lot
Most welcome 😊
I love you .it helped me so much .you just got a like and a sub
u are really something else great job
Wow I prefer this lecture it's very simple and understood ❤ thanks sir
Glad to hear that
thanxs a lot for giving a best idea
You lost me at "Hi everybody" :/
That is absolutely amazing 💕
In your 5 ohms resistor (horizontal) how can we know the positive and negative side of the resistor
to find which side has a higher electrical potential you need to find the direction of the current through that resistor. Positive current (as defined in physics) goes from higher potential to lower potential.
@@PhysicsNinja understood. My lecturer made a 2 hours video about this and I couldn’t grasp a thing. You made me understand the concept with a few minutes video. Thank you 🙏
how do i use to calculate this circuit using matrix and how do i arrange in matrix form, like how to arrange the 3 equations in the video in matrix form
(a1 b1 c1, a2 b2 c2, a3 b3 c3) (x, y, z ) = ( a, b, c ) take the inverse of the 3x3 matrix on the other side and multiply
