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.

[@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

[@niroos6819]

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

[@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.

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

[@gordonloo2867]

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

[@aarya-f4v]

goldmine this was very helpful, i went through dozens of lectures and this one was the only one that could explain me with clarity!

[@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

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?

[@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.

[@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!

[@taladiv3415]

I like the energy and flow in these videos. 💪

[@daniellee8015]

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

[@PhysicsNinja]

Thank you so much.

[@philipjohn1338]

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

[@kasiorap]

ten seconds into the video and i love this man already

[@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.

[@im_jenkins]

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

[@jamieblankenship1942]

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

[@shayannassabi572]

My teacher at school doesn’t know how to teach. You are amazing! Physics ninja to the rescue!

this channel has been a lifesaver

Learned KCL & KVL a while back, this served as a great review for me, keep up the great work!

literally thank you so so much, i have a test on circuits tomorrow and needed this!!

[@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

[@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?

[@Ibrahim-tq8hv]

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

[@madboycal7859]

This concept did not click until I watched this video. Thanks Physics Niinja 😎

[@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!

[@ebbyluis7090]

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

You literally saved my day .Thanks

[@jameswilliam5487]

Now am back on track thank you

[@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.

[@سبحاناللهوبحمده-س4غ7ج]

in 11:00 Why did we choose to eliminate I2 and I3, is it always like this or what?

[@spadezap9728]

it's so we can solve for one variable which was I1.

[@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

[@MNKofficiel]

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

[@PhysicsNinja]

DC Circuits - Power Dissipated in Resistors kzbin.info/www/bejne/kJPdeJxpes6qjNE

[@utmw]

life saving, thank you!

[@Jimmyillusionz]

In your 5 ohms resistor (horizontal) how can we know the positive and negative side of the resistor

[@PhysicsNinja]

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.

[@Jimmyillusionz]

@@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 🙏
