CHUA'S CIRCUIT
 
APPARATUS
Chua's circuit
 101-02-C1
two 9 V batteries
 202-02-D1
oscilloscope 202

DESCRIPTION
Use the scope to display VC1 vs VC2.  Vary the resistance to show the transition from periodic to chaotic behavior. Several period doublings, chaotic regimes, and periodic windows can be observed.


NOTES
For the interactive display, use a panel-mounted potentiometer.


The Chua diode is a nonlinear negative resistor.  It is constructed from two op amps, several resistors, and two 9 V batteries.  See the reference below.
