    Ohm's Law????????
    From: Doug Royer

    George,
    Where or how did you come up with "Ohm's Law only applies to those
    conductors that Ohm's law applies to.Try a filament lamp, zinc oxide
    resistor,a semiconductor junction etc. Ohm's Law applies to none of
    these.Nor does it apply toa contact between 2 oxide corroded metal
    surfaces".
    Am I missing something?
    Ohm's Law most assuredly still applies to everything you mention.
    Any PN junction is nothing but a variable resistor.It doesn't operate in a
    linear fashion but it is still subject to Ohm's Law.
    You'd better guess again about your statement reguarding it doesn't apply to
    contacts between 2 corroded metal surfaces either.
