I messing around reviewing the basics and I came up with some idea about
using a voltage divider to run a load and negative resistance to cancel out
the loading effects... the idea follows
R1
|
+----+
| |
R2 RL
| |

G G
If, say, we let R2 = -R1*RL/(R1+RL) then the total resistance is 0... we
could then put in a series resistance with R1, say, Rs that fixes the
current as V/Rs.
I'm curious as to how pratical this is? Is it possible to "sense" the
resistance RL and to have some device that can make negative resistance
following that equation for R2? I don't know much about negative resistance
except that tunnel diodes exhibit it for certain ranges and stuff.
Now that I think about it you don't even need to use a voltage divider
just having R2 in series with RL and R2 = -RL would do the same.
Any ciruits that use this "principle"?
Thanks,
Jon
