Kirchhoff's Current Law, Junction Rule, KCl Circuits - Physics Problems

This physics video tutorial provides a basic introduction into kirchoff's current law or junction rule. It explains how to calculate the missing current flowing into or out of a junction. A current flowing into the junction is given a positive sign and a current flowing out of a junction is given a negative sign. This video contains plenty of examples and practice problems on kirchoff's junction rule for KCl circuits.

HAPPY TEACHERS DAY cuz you taught us more than our college teachers xd

[frischrank]

Wow, you are a lifesaver TOCT. Every time I am stressing about not understanding anything and I google it, you're always the first to show up with informative teaching. Thank you.

I owe you everything mate!I had no literally no math or physics experience as a stupid teenager skipped school became a chef and lived life, fast forward to a career change, studying engineering and in a year or two its gone from not even understanding basic algebra or sohcahtoa (my own fault) etc. To scores of 90 in phys I and managing though Phys II. Looking back this is just unbelievable, there's been many mental breakdowns through the way and hundreds of not thousands of hours of grinding, but ill go so far as to say your work here has literally carried me through these courses, I cant thank you enough.

In high school, I just learn math, English, literature so I have no roots in physics. but when I come to university I myself turned into electronics engineering so I struggle with lots of subjects. you bring Physics knowledge back to me another time. your explanation is very easy to absorb .your fundamental series help me understand the ways electricity run. thank you so much.

Bro, you're a real one. I never finish a video less enlightened. Thanks a lot for such helpful content; God bless ya... richly

[Rodrigo-jvsl]

man I am really thankful for these videos you make. Physics is challenging but you make it simple and not overly complicated.

[faichalayeva]

Thank you!! Congratulations for 1M👍🏼👍🏼 Good luck!

[waleedbro]

I am speechless to what you are presenting to us may Allah bless you and improve as long as you are living 🥰🥰❤️

[tedlahm]

Fantastic explanation. A little fast on the math equation, but we get it.

[snowjix]

I wonder what Kirchoff's Previous Law was like. Cant have been good since he needed a new one.

[LarryLovestein]

Wow a whole lecture condensed into what I need to know. Who would have thought

[sammymomanyi]

I like your presentation, very excellent tutorial. Keep it up.

[pumpkingolem]

thanks you so much every time i fail to understand something or miss a lecture you have a video to help you are great

[Sky-pgxy]

Im confused. What does Potassium Chloride gave to do with Current Law?

[itachu.]

its been seriously a long time since me wathcing you, thanks man these short videos really help me out for my revision.THANKSS!!

[ahmadhafiz]

Came here just to learn how to pronounce kirchoff

[RewayiElizabeth]

This helped me. A lot thank you ❤🎉🎉i really appreciate
I recommend u guys to watch this

[shehrivan]

I'm first stage student of computer and communication engineering CCE collage and i don't understand anything from my teacher I think your videos can help me and sorry for bad English 😅 2023/1/26

[ibrahimfikri]

Out of curiosity tho, for the last question, what do you do if the directions may or may not be different ?

[EnockemzeeZulu]

Wonderful ❤ tutorial I think need more of this types of tutorial
