Solving Circuit Problems using Kirchhoff's Rules

[@elliotluedtke7630]

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.

[@niroos6819]

i love how enthusiastic you are about this thanks a ton for making it simpler

[@lea-anon]

I was struggling with Kirschoff's Law but this really made me realize how simple it is! Thank u mr. ninja appreciate it

[@Pap3rKoI.]

same here

[@emperor_talon4200]

This is literally the best physics lecture I’ve gotten in physics so far! Thank you so much!

[@PhysicsNinja]

Thank you so much for the kind words.

[@worklikehell3274]

@@PhysicsNinja thank you for telling me which my teacher couldn't do in 2fuckin years

[@loganstone2862]

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

[@PhysicsNinja]

Thanks for watching!

[@santanuhalder4188]

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.

[@BeekersSqueakers]

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.

[@Dailymailnewz]

@@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?

[@daniellee8015]

Hands down the best explanation I have ever seen. Thank you so much sir, you are the GOAT

[@PhysicsNinja]

Thank you so much.

[@taladiv3415]

I like the energy and flow in these videos. 💪

[@gordonloo2867]

After 3 videos on this topic, yours is the one that helped me finally get the hang of the rules. Thanks!

[@r3dy627]

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!

[@dogle367]

I love you. Seriously. It's amazing how fast things can click when they're explained well. Thank you!

[@JeffHogge-n1f]

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.

[@philipjohn1338]

Watched hundreds of videos but this one makes the most sense.

[@simonmburu6892]

I have not yet had a class on these multiloop circuits but I've already understood the concept....thanks to you physics ninja

[@nikocvitanic7701]

why are you watching the video then?

[@rebekahm6672]

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.

[@Linogiven-O]

School teachers are stupid. they don't teach properly.

[@lavk2777]

I feel like I stumbled upon a pot of gold. You're seriously the greatest. Thank you so much.

[@PhysicsNinja]

Happy to help!

[@im_jenkins]

I learned more in this 20 minute vid than my hour long class. Well done

[@texasnewt]

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!

[@Ibrahim-tq8hv]

Three days stuck on this topic this man shows out like fucking batman and saves the day!

[@elizahlakao5539]

I really understand that video. This video had perfectly clarified some of my doubts. I really love it. Thank you Physics Ninja.

[@nasthehustler2539]

I have all the information from the book but just 😢 can't trust my methods I'm also grateful I found this video

[@willbooker6287]

For anyone who has taken linear algebra - you can do all the algebra with matrix row reduction! much neater to work through that way

[@ebbyluis7090]

Just want to say thanks for this great Video. Everything is simplified and very easy to understand.

[@peterheerens3093]

It's been a while (40 years) since I learned this stuff at polytechnic. Still got it though :-)

[@cherryclorox7717]

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

[@samuelpelletier1646]

Thanks you you helped me passed my semester

[@carolineseffen7458]

Nice and amazing and very simplified video , thanks a lot

[@PhysicsNinja]

Most welcome 😊

[@bigbrother9531]

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.

[@carultch]

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.

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 very much! You've cleared all the questions in my mind regarding this topic.

[@ReyneMba]

Excellent explanation thanks

[@another-learner8677]

I am taking a circuits 1 class and the professor went over concepts like this with few slides and no examples at all. If you are in same situation please watch videos like this because you are on your own. It is very unfortunate where a highly paid professor at a big university does not cover any examples and expect the class to do good in exams.

[@aDiamonda]

all respect man. better than my teacher!

[@venkat4137]

Well explained and you deserve thumpsup and subscribed

[@natthekiwi7074]

My teacher taught that the positive to negative leads to an increase in voltage which means all my signs are the exact opposite of yours. It leads to the same answer but I was wondering it if matters conceptually.

[@lordandsaviour8270]

Mine too , that's why I got confused

Hwello nice class but i feel the calculations couldve been much more simplified if you had solved for I1 in the first eqn and I3 in the second and then sub in KCL

[@alberteinstein791]

Thanks a lot for explaining very clearly

[@astralnovaNeel2002]

Thanks a lot Ninja...This video has helped me a lot....You are doing really good.

[@azikiwewilliams3187]

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?

[@seraajregal4663]

Tenth video i watched before getting thr concept

[@simplicityfx70]

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!!!

[@lethabodumpiiey4150]

Resistors can't be equated to one when you have multiple batteries that have random different directions in different branches

[@nikiniewerth8148]

OMG, you are a life saver

[@SeanMcDonnell33]

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?

[@are2515]

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!
