The point remains that NON OHMIC RESISTANCE caused by a nonlinear
relationship between voltage and current clearly does NOT obey Ohm's law.

The fundamental problem is that there are two types of electricity and
electronics taught -- those for high schools, military, and technicians
versus those for engineers.

The technician Ohm's law is dead wrong most of the time in most of the
circuits. Just like the electron flow current is the EXACT OPPOSITE of
the one on the IEEE tie clasp.

For real engineers, Ohm's law only rarely and approximately applies.
It is ALWAYS suspect.
