Can someone change the current divider law picture. The law is Rx_current_unknown = Itotal_x(R_total/Rx) the picture has an extra R total at the bottom of the denominator —Preceding unsigned comment added by 99.249.120.189 ( talk) 20:12, 9 January 2011 (UTC)
I am not shure what needs to be cleaned up in it. i agree that some pictures would help but since i cannot host any..
as for merging it with the resistors i would have to disagree. It does not mention how to find current through a resistor.
Ohm's law talkes about how voltage equals current divided times resistance
Somebody add a proof please? i had to figure it out on my own — Preceding unsigned comment added by 94.209.183.26 ( talk) 16:31, 18 September 2014 (UTC)
It is true that the CDR and VDR and Ohms law are the very basics of electrical enginering. however i disagree with you comments that they should be merged into the ohms law.
Current Divider and Voltage Divider do use ohms law and are a pratical application of it. however they are seperate elements and most textbooks i read have them divided up into different sections as well. 08:19, 17 December 2005 (UTC)
There seems to be another way of using the current divider rule. The formula is slightly different. I suggest adding this to the article as well if this method is correct.

Since current division is the dual of voltage division, I propose we rename this article for consistency. Plus I don't think I've ever heard the term "current divider rule". People usually just say "current divider". -Roger ( talk) 17:01, 6 January 2008 (UTC)
According to my book the right way to find is where . If we use the formula (the one that actually is in that paragraph) shouldn't include and this is not clear from there. I also took the values from an exercise on the book and I checked with Python that both the methods work.
>>> def par(*res):
... return 1 / sum(1/r for r in res)
>>> r1 = 10
>>> r2 = 2
>>> r3 = 20
>>> it = 4
>>> # i1 should be equal to 0.6154 ampere
>>> # method 1
>>> rt = par(r1, r2, r3)
>>> (rt/r1) * it
0.61538461538461531
>>> # method 2
>>> rt = par(r2, r3)
>>> (rt/(r1+rt)) * it
0.61538461538461531
As you can see in the method 2 there are only R2 and R3. —Preceding unsigned comment added by 130.232.126.213 ( talk) 20:24, 11 October 2008 (UTC)
I think there still is an error. Take the example , for two resistors in parallel. If we do this, and note that we get, by insertion, , and extending with , we get: , which is NOT equal to what the textbook gives us, which is, as noted above, , for the case of two transistors in parallel. So we should either change the definition for in the article, or write another formula for the voltage division (the equation for division and the definition for equivalent resistance are inconsistent).
Can someone please double check I was correct in making my last edit? I changed RTotal to RX — Preceding unsigned comment added by 2601:880:C100:69D0:C414:6EEF:8F2A:646A ( talk) 22:50, 7 December 2016 (UTC)

Hi! A friend of mine has pointed out to me that maybe should be edited in and in , and the sentence "where ZT refers to the equivalent impedance of the entire circuit" is probably wrong. Could someone have a look? Thank you, -- Epì dosis 10:32, 20 May 2019 (UTC)
In response to above: I believe both are correct. But the original form of is (in my mind) extremely confusing. While Nilson/Riedal use this form (I went and checked my copy as I didn't believe the reference at first), every circuit division rule I've seen (besides this one) uses the form of , because in general, always refers to the entire circuit (or at least, the entire parallel portion). Defining it to be the other way is just... odd.
