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.
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?
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.
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 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.
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!
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!
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)
You could have proved it by looping the junctions and the then showing the flows. Or the voltage drops . Nice refresher for something I learned years ago.
There's also the method of superposition, which simplifies the algebra to plug-and-chug arithmetic, so you don't need to solve a system of equations. The way it works: 1. Pick one of the energy sources of the circuit. 2. Replace all the other voltage sources with short circuits, and all the other current sources with open circuits, to "turn them off". 3. Use resistor combinations and voltage dividers to solve for the voltage at a desired point. Identify it with the point and the ID number of the voltage source. Put that aside for later. 4. Repeat for all the other sources 5. Add up the voltage at the desired point due to each of the sources, to get the total voltage at that point.
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
how do we know that the resistors cant be replaced with a equivalent one? and one more is there any case that both voltage and current does not remain constant? i appreciate ur fantastic work!!!
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?
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 🙏
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.
I was struggling with Kirschoff's Law but this really made me realize how simple it is! Thank u mr. ninja appreciate it
same here
i love how enthusiastic you are about this
thanks a ton for making it simpler
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
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!

goldmine this was very helpful, i went through dozens of lectures and this one was the only one that could explain me with clarity!
After 3 videos on this topic, yours is the one that helped me finally get the hang of the rules. Thanks!

I like the energy and flow in these videos. 💪
I love you. Seriously. It's amazing how fast things can click when they're explained well. Thank you!

ten seconds into the video and i love this man already
Hands down the best explanation I have ever seen. Thank you so much sir, you are the GOAT
Thank you so much.
Watched hundreds of videos but this one makes the most sense.
Three days stuck on this topic this man shows out like fucking batman and saves the day!
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 learned more in this 20 minute vid than my hour long class. Well done
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?
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 feel like I stumbled upon a pot of gold. You're seriously the greatest. Thank you so much.
Happy to help!
You have the most engaging teaching voice. It's as if I am at a fighting match but for physics! Love it! :)
this channel has been a lifesaver
literally thank you so so much, i have a test on circuits tomorrow and needed this!!
Learned KCL & KVL a while back, this served as a great review for me, keep up the great work!
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
This concept did not click until I watched this video. Thanks Physics Niinja 😎
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!
I liked the video before I even started watching it I can sense greatness
So kind, thank you
straightfoward, subscribed.

literally saved my time, such a simple and detailed explanation! Gottta give this video a like, thank you!!
What an explanation I didnt understand this thing for a whole term now I know it it turns out to be easy
Sir, your energy was so good in explaning love from india
i think you may have just actually saved my life
Thank you iam from Egypt i cant speak English well but that's really was helpful you are better than my own teacher
Happy to help!
Thank you so much! I wish I have a professor like you
nice sir, watching your video from Pakistan and your teaching method is very good.
Thank you
You have made me a loyal fan. Great job with the explanation!
Glad to hear it!
Bro your algebra skills are on point respect
I FINALLY LEARNED HOW TO DO THIS BECAUSE OF THIS VIDEO THANK YOU ! ! ! ! ! ! ! !
Beautifully explained. Thank you so much.
this video was very helpful to figure this out, way better than my uni lecture, thank you very muchly
For anyone who has taken linear algebra - you can do all the algebra with matrix row reduction! much neater to work through that way
thanks, easy explanation didn't even have to finish the whole video
Wow! I can't believe it was that simple. Thank you so much!
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.
i have an exam in exactly 7hours, ty I finally understand
This was great 😭😭😭😭 thank you for saving us 🙏
Very nice explanation bro... Love from an Alevels student of Pakistan 🇵🇰 👌🏻😍❤️
Amazing, it was a quick and exact explanation of a lengthy method. 🚩🚩🚩🚩🚩
Thank you so much.
Thanks for the help. I was stuck not knowing how to do my lab.
thanks you made simple its easy to understand
Thank you so much!!!
This was so helpful and so enjoyable! Bravo
This video is just awesome. I like your explaination sir God bless you
Best video I've watched on this. Thank you
Thank you, physics ninja 🙂👍
Wow I prefer this lecture it's very simple and understood ❤ thanks sir
Glad to hear that
This topic was always super confusing for me, but I finally get it now. Thanks a lot!!!
I also
Well explained and you deserve thumpsup and subscribed
Nice and amazing and very simplified video , thanks a lot
Most welcome 😊
Thank you very much! You've cleared all the questions in my mind regarding this topic.
It's been a while (40 years) since I learned this stuff at polytechnic. Still got it though :-)
I like your videos, I think every body will.
Thank you so much!
Excellent explanation thanks
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
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)
it will be a pleasure if yuo could made another one of most complicated and hard
thank you so much, i literally spend 2 days to figure this out.
Thank you for this explanation !!! Hopefully I will not fail my exam tomorrow !! Fingers crossed !
Fantastic video, thanks for sharing you knowledge
My pleasure!
You literally saved my day .Thanks
you saved my life, thank you
Now am back on track thank you
Thanks you you helped me passed my semester
all respect man. better than my teacher!
Thanks for your support! You’ve got this.
Legends watching this 5 hrs before an exam
Very clean explanation, loved it!

How do we calculate the total power dissipated for this circuit?

Thanks a lot for explaining very clearly
Better explained, more enthusiasm then Khan Acadamy and all those other TH-camrs. Great video, Keep it up :)
That was really really helpful, you're awesome
in 11:00 Why did we choose to eliminate I2 and I3, is it always like this or what?
it's so we can solve for one variable which was I1.
Thank you so much for that explanation 😊
amazing! thank you. Perfect for mcat review
Thanks a lot Ninja...This video has helped me a lot....You are doing really good.
Thank you so much for the helpful video

Best explanation 🎉
Thanks a lot 😊
Dude, Thanks a lot for this awesome explanation!!
life saving, thank you!
how do we know that the resistors cant be replaced with a equivalent one?
and one more is there any case that both voltage and current does not remain constant?
i appreciate ur fantastic work!!!
Resistors can't be equated to one when you have multiple batteries that have random different directions in different branches
thanks a lot sir! a real learning early morning is best!
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?
This video is great at explaining this concept.
OMG, you are a life saver
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.
