# QUESTION: What is a "locally active resistor"?

Hi all

I came across the article on "Chua's circuit" in Wikipedia (at ). This
circuit "exhibits classic chaos theory behavior" even though it is
composed only of "standard components" (resistors, capacitors,
inductors).

This article also lists the criteria that a circuit must meet in order
to display chaotic behaviour. One of the criteria (#2) is:
One or more locally active resistors

The question I wanted to ask is, what is a "locally active resistor"?

Aren't all resistors in a circuit locally active? Or can there be
"remotely active" resistors, and in what kind of situation would that
be?

==================================================================

The simulation applet was interesting. The circuit seemed fairly stable for
higher values of R, and the intensity of oscillation diminished. But when
the value was lowered the pattern expanded and eventually hit the supply
rails. Order was eventually restored by raising the value. It seemed like a
resonance phenomenon.

there are never active resistors capacitors coil SWITCHES and so forth. They are all passive conponents. MAYBE THEY ARE FROM mars AND BECOME ALIVE.
