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.

    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.

    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.

    8:50 Is "I4 = 2(I3)" just an arbitrary solution or does it follow an underlying principle? Because I tried "I4 = 3(I3)" and I only got -6A for the value of I3 while you got "I3 = -8A" What is the explanation for saying tht I4 is twice the magnitude of I3? Or is it part of the given / problem? Thank you!

    is it correct for the saying that the summition of current entering and leaving a point is equal with zero? i think this rule is for voltage, not for current.For current;the current entering a point is equal with the current leaving that point.
