Hi Ratch,

What do G. Ohm, J. Maxwell, N. Tesla, J. Watt, Coulomb, Hertz, ...
all have in common?

They were dead and buried before the various engineering and physical
societies named equations and constants in their honor.

Tesla's body of work far exceeded the study of static magnetic fields;
Watt worked on steam engines, and developed the horsepower, he knew
nothing of electricity, and the metric system; Hertz was way more than
a cycle per second; and Ohm worked on more than that one equation
for resistivity.

These men were honored by various societies for their work in the
sciences. It is quite natural that the physicists and engineers
would honor different parts of these guys lifes works.

What does the fact of receiving awards and honors posthumously have to
do with what we are discussing?


If you ask engineers what is Ohm's law, they will say E = iR,

Only because they learned it that way. If you explained the misnomer,
then what would they say?

if you ask physicists, they will give a long boring diatribe about
bulk resistivity, and cross sectional areas.

No they won't. Cross sectional areas have to do with the Resistance
formulas, not the real Ohm's law.

If you asked George's
wife and children, they would come up with yet another entirely
different answer.

Pure speculation. Was he even married? Would his family understand
the question? Would their answer have any meaning?


This is not the first time engineers and physicists have differed
in their approaches to academic study. Just think of the different
meanings of E and V, i and i and j, ....

A misnomer is not a study approach. Voltage and current have the same
meaning throughout science no matter how many different ways they are
studied or explained by representative analogs.


So, just as you can quote a couple of physics text books and "prove"
that ohm's law is one thing, I can quote an equal number of
engineering text books that say otherwise.

Those texts I quoted are really good college level textbooks. Would
the authors you would quote be able to defend their writings after being
shown what I believe is the error of their ways? Ratch

I*R is not Ohm's law, but the V vs. I linearity, if present, is the law.
