Wow never really thought of it like that.
After you mention a lot of the items I can see from their actions that
they would have to be no linear.  I just never really thought about
things being nonlinear.  Seems that while things being nonlinear might
make things hard to design at times we also have a lot of wonderful
things in our lives because of the nonlinearity.

Guess I will have to go on singing...............
Living in a nonlinear world <to the tune of modanna material world>

Thanx for the thoughts
I never really took the time to see the obvious.

Luke,

They're everywhere - nature seems to favor nonlinear behavior. Because
of
this, it can be very challenging to design a piece of equipment that's
truly linear over a wide operating range. Virtually every electrical
component you encounter is actually nonlinear to some degree. However,
most
components normally do not exhibit any negative resistance
characteristic
unless they become electrically overstressed in your TC and irreversibly

break down... :^)

All passive components are somewhat nonlinear. Cored inductors saturate,

and many types of resistors and capacitors will change value as a
function
of applied voltage. ALL semiconductors, vacuum tubes, and cold cathode
(gas
tube) devices are also inherently nonlinear, particularly as you
approach
zero volts, approach voltage or current limits, or reverse polarity.
Other
common components that show marked nonlinear characteristics include
surge
suppressing MOV's, incandescent lamps. Neon lamps, fluorescent lights,
or
flash lamps display nonlinear negative resistance characteristics in
some
operating regions, and nonlinear positive characteristics in others.

Best regards,
