Re: Ohm's Law



Ohm's Rule of Thumb would be a better name for this relation which
ASSUMES (tacitly, perhaps) that R is constant.

'Twould be far better to refer the the LAW of Special Relativity
(rather than 'Theory') and the LAW of Evolutiuon.

Only by popular usage can such changes occur. IUPAP doesn't CARE what
we call what. (except for naming elements?)

Good point - I don't like it, but we do that with other definitions (eg.,
it is kosher to regard one or more of Newtons "laws" as definitions).

More importantly, if R= V/I is a statement that the resistance is
independent of voltage, where is the definition of resistance (R)?
