Hi Luke

I enjoyed this thread very much, learning a lot about different views of 
negative DIFFERENTIAL resistance as Ed Phillips was naming it. And I would 
never like to discourage you asking basic Q's, the way you do it.

But why, regarding this 100W light bulb, don't you take a Variac plus 
Ampère- and Voltmeter and perform a series of experimental [V,I] 
measurements, in order to verify that nonliear V,I curve by your own 
experience? - A simple mind (like myself ;-) ) might calling it beeing 
happy about an easy result...

BTW, some other examples of nonlinear resistors:
NTC (= Negative Temp. Coeff. R's), used i.E. to limit switch-on current.
PTC (= Positive temp. Coeff. R's), having a steep rise of resistance in a 
limited Temp.-range, used i.E. as current limiting devices.
VDR (= Voltage Dependent R's) ...used in the form of MOV's in Terry's 
filter, in order to limit the voltage on NST's.
LDR (= Light Dependant R's) change resistance by light.

Cheers, Kurt
