Re: R = V/I ?

[Rick Tarara <rbtarara@SPRYNET.COM>]

If one wants to stay within the 'philosophy' that resistance is a
temperature and geometry dependent property of the material, then what one
would say is that the light bulb has a well-defined resistance for every
temperature encountered within a given range of currents.  The I-V graph is
then a convenient way to MEASURE this resistance.  ;-)
