While correct and true in all
cases, those formulas are NOT Ohm's law, and it is wrong to
call them that.

Dude, go back to school, Algebra 1. V=IR I=V/R R=V/I etc.
The equation can be rearranged to any of the others by simple
multiplication and division by whichever variable.

I believe everyone on this newsgroup can isolate each of the
terms algebraically. What is your point? What don't you
agree with? What is incorrect? Be specific. Ratch


I think, for "practical" electronics, the "ohmic" and "non-ohmic"
properties of resitance and its implication in the Ohm's Law equation is
largely depreciated. All resistors are likely assumed ohmic except for
specialty devices or applications, most of which deal with temperature and
not voltage. Personally, I find the voltage-dependant-negative-coefficient
resistances (such as carbon fiber) particularly interesting.
