Re: Internal resistance



When I studied electrical engineering
twenty-some-odd years ago,
R = V/I was called "resistance",
and r = dv/di was called "dynamic resistance".

Terminology point: On the side of the tracks
where I grew up, "resistance" means the small-signal
resistance,

R := dV/dI

as discussed at
http://www.av8n.com/physics/resistance.htm

I am beginning to suspect that Ludwik might have
been using some other definition of R.
