ＲLC Circuit Ｒesonance Experiment is a compulsory experiment for engineering students and physics students of colleges and universities．It also plays a very important role in practical application．Meanwhile，the way basing on LabVIEW virtual instrument platform，combining virtual instrument technology with traditional experiment，is also one of the important developing directions of physical experiment． The ＲLC circuit characteristics were studied with virtual instrument technology，and the virtual instrument test-platform was built to test the amplitude-frequency characteristic of the ＲLC circuit，and the amplitude-frequency characteristic and resonant phenomenon of the ＲLC circuit were studied．The way combining virtual experiment

with traditional experiment enables students to intuitively feel the advancement and convenience of new technology on experiments，it also improves the efficiency of experiments，and creates a new situation for the cultivation of students’thinking way.
