Abstract: Through comprehensive experiment design of circuit principle,the paper applies software simulation experiment and traditional hardware experiment to design experiment of full response of the RLC series circuit under four kinds of situations:under damping、critical damping、over damping and optimal damping.The voltage changes of the capacitor in four situations are shown.The experiment results are agree with each other.The practice experience of circuit principle experiment can arouse students interest of study and enhance the students ability of operation and cause experiment content to be more direct-viewing,vivid and easy to be grasped.It plays a good role in deeping the reform of circuit principle experiment,a promotion of the research,reform of experiment teaching contents,experimental teaching mode,experiment teaching method,the interest of studying,the improvement of college students’ comprehensive ability and practice ability.
