Abstract: Aiming at the experiment of Wheatstone bridge and Kelvin bridge,the current intensity through the alvanometer in the single bridge and double bridge is expressed by a unified formula. Based on LabVIEW,a platform of virtual simulation experiment for DC bridge with the full function of Wheatstone and Kelvin bridges is designed. The two bridges are applied to measure the middle value resistance and low value resistance separately. Inthe classroom,the virtual instrument is used for the experiment teaching,which is useful to explain the difficulty of teaching and improve the teaching quality effectively. The sharing of the application ( EXE) of the virtual simulation experiment on the campus network provides autonomous learning space for students. It is also used for informationized teaching for college physics experiment.

Key words: DC bridge, LabVIEW, visual instrumentation, informationized teaching
