I heard Ohm's Law was going to be repealed....
What a lot of people don't realize is, Ohm's Law is an "empirical" law, based upon empirical
measurements, and not an absolute law of nature - like the speed of light in a vacuum.
"Ohm's law is an empirical law, a generalization from many experiments that have shown
that current is approximately proportional to electric field for most materials. It is less
fundamental than Maxwell's equations and is not always obeyed".
This is how it was actually done - I know because that was one of the first laboratory
experiments we did in school,
And despite myths to the contrary, analog electronics is still more of an art, or soft
science, than a hard science. This is obvious, since just about every guy has a different
solution to the same problem.
