Only if you define resistance that way. For non-linear circuit
elements it's a pretty meaningless thing to say.

Absolutely. And if we dare mention in this thread that internal resistance
of a battery is dI/dV (rather than I/V), then god knows what chaotic
argument that will create amongst the cognoscenti who think that a battery
is a big bucket full of electrons!

WHOOPS - meant dV/dI and V/I, sorry!
