Kirchhoff''s Current Law
Here in this simple single junction example, the current I T leaving the junction is the algebraic sum of the two currents, I 1 and I 2 entering the same junction. That is I T = I 1 + I 2.. Note that we could also write this correctly as the algebraic sum of: I T – (I 1 + I 2) = 0. So if I 1 equals 3 amperes and I 2 is equal to 2 amperes, then the total current, I T leaving …
