Re: Ohm's Law

Typical EE's DO in fact speak often of the DYNAMIC resistance of
non-linear (i.e. interesting) devices. The dynamic resistance is
defined to be delta V / delta i at a specific 'load point'.

(4) This is the one I quibble with the most. If a device is non-ohmic, then
I would not even say it has a resistance. I don't think the typical
electrical engineer would speak of an operating diode or transistor as
having a resistance even though it has a potential difference across it and
a current through it.
