SUMMARY

The discussion centers on the concept of negative resistance, specifically referencing the composite configuration of carbon nanotubes and the historical context provided by Gabriel Kron's work with the US Navy's "Network Analyser." Participants clarify that while static negative resistance is impossible according to the laws of physics, negative differential resistance, as seen in tunneling diodes, is a legitimate phenomenon. This distinction is crucial for understanding the implications of negative resistance in electronic components.

PREREQUISITES
  • Understanding of negative differential resistance in electronics

From wikipedia, there is a reference to "composite configuration of carbon nanotubes which appears to exhibit anomalous results which resemble a static negative resistor", and "Gabriel Kron, while a scientist for General Electric, is thought to have built a negative resistor for the US Navy's "Network Analyser"."

Is there more to this (or is it a 'fringe' case)? If the latter, does it really belong in wiki?
 
Physics news on Phys.org
it's not a fringe case. look up the tunneling diode link at the wiki article. tunneling diodes do have a (U,I)-region like that.
 
Tunnel Diode is not a static device, its Imposssible within the laws of Physics to have a static negative resistor.
 
As far as I can understand the Wikipeida arttical it's talking about negative differential resistance and therefore I don't really find it unbeliavabele (perhaps a bit unusual).
 
Yes, negative differential resistance means that although it has a positive
resistance, a slight increase inthe voltage causes less current to flow.

A true negative resistance supplies power.
