Form the teaching point of view for the electric cirucit course, approaches to realize Chuas circuit and Chuas diode are introduced and the simple working principle of Chuas circuit is discussed. An experimental scheme to view the period 1, period 2 limit cycles and the single scroll and double scroll chaos attractors of Chuas circuit is given. The results of the experiment show that Chuas circuit has rich dynamical behaviors and its structure is very simple. By doing the experimental study on Chuas circuit combining with the teaching of the nonlinear circuit, the enthusiasm for students studying the course will be excited and the base for their further study and research on the nonlinear field will be established.
