Solving Circuit Problems using Kirchhoff's Rules
HTML-код
- Опубликовано: 1 янв 2018
- 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.
I was struggling with Kirschoff's Law but this really made me realize how simple it is! Thank u mr. ninja appreciate it
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!

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?
i love how enthusiastic you are about this
thanks a ton for making it simpler
After 3 videos on this topic, yours is the one that helped me finally get the hang of the rules. Thanks!
I feel like I stumbled upon a pot of gold. You're seriously the greatest. Thank you so much.
Happy to help!
I like the energy and flow in these videos. 💪
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!
Watched hundreds of videos but this one makes the most sense.
Thank you so much! I wish I have a professor like you
You have the most engaging teaching voice. It's as if I am at a fighting match but for physics! Love it! :)
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.
ten seconds into the video and i love this man already
Thank you very much! You've cleared all the questions in my mind regarding this topic.
literally saved my time, such a simple and detailed explanation! Gottta give this video a like, thank you!!
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
straightfoward, subscribed.

I learned more in this 20 minute vid than my hour long class. Well done
Three days stuck on this topic this man shows out like fucking batman and saves the day!
This topic was always super confusing for me, but I finally get it now. Thanks a lot!!!
I also
Learned KCL & KVL a while back, this served as a great review for me, keep up the great work!
For anyone who has taken linear algebra - you can do all the algebra with matrix row reduction! much neater to work through that way
Wow! I can't believe it was that simple. Thank you so much!
Just want to say thanks for this great Video. Everything is simplified and very easy to understand.
Thank you
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!
Dude, Thanks a lot for this awesome explanation!!
Sir, your energy was so good in explaning love from india
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.
What an explanation I didnt understand this thing for a whole term now I know it it turns out to be easy
Bro your algebra skills are on point respect
Best video I've watched on this. Thank you
thanks a lot sir! a real learning early morning is best!
This concept did not click until I watched this video. Thanks Physics Niinja 😎
I FINALLY LEARNED HOW TO DO THIS BECAUSE OF THIS VIDEO THANK YOU ! ! ! ! ! ! ! !
Beautifully explained. Thank you so much.
This video is great at explaining this concept.
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 so much, i literally spend 2 days to figure this out.
You literally saved my day .Thanks
Thanks a lot Ninja...This video has helped me a lot....You are doing really good.
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.
Amazing video, extremely helpful
Great and simple way to teach.
thanks, easy explanation didn't even have to finish the whole video
very helpful. keep doing complex examples
i think you may have just actually saved my life
Thank you for this explanation !!! Hopefully I will not fail my exam tomorrow !! Fingers crossed !

THANKYOU SO MUCH! 💕
It's been a while (40 years) since I learned this stuff at polytechnic. Still got it though :-)
thanxs a lot for giving a best idea
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
Wow. What a good video.
Thank you so much ❤️
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!
