[Elecraft] Negative Resistance????

Thu Jul 17 17:13:01 2003

I'd have to look at my manuals...but it sounds like a charge on a
capacitor...if you have a voltage present on a circuit that you are
trying to measure resistance...the meter depending on model will show it
in a negative fashion.  It is also possible that if you are working with
florescent lighting nearby, the traces are picking up the field and
inducing a small voltage.

What am I missing here?  Negative resistance?  What are we talking about
here?  I always thought that you either had resistance or there was no
resistance.  You cannot have no resistance because you will always have
some...at least in the physics in my head.  To me, negative resistance
is one the other side of the Y coordinate and could only happen in
mathmatics and not in real life.  Conductance?  No, I do not thing that
is what we are talking about either.  HMMMMM.  Negative resistance
doesn't make sense to me although I guess if they are using those
special ceramic compounds cooled down to -254 degree or something.  Even
then, I just can't get idea of negative resistance.  Negative resistance
strikes me a bit funny.

What am I missing here?
