Solving Circuit Problems using Kirchhoff's Rules

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.

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

[niroos]

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

[emperor_talon]

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

[elliotluedtke]

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

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!

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

[taladiv]

I like the energy and flow in these videos. 💪

[dogle]

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

[TaeTae-bocv]

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

You have the most engaging teaching voice. It's as if I am at a fighting match but for physics! Love it! :)

[philipjohn]

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

[curesnow]

Thank you so much! I wish I have a professor like you

literally saved my time, such a simple and detailed explanation! Gottta give this video a like, thank you!!

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.

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!!

[elizahlakao]

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

[strawberrysingsthings]

Wow! I can't believe it was that simple. Thank you so much!

[kasiorap]

ten seconds into the video and i love this man already
