| Abstract: | This paper measures the change of copper resistance with the changes of length using Kelvin double bridge. It discusses the advantages of using matlab software to process the experimental data, and then gives the resistivity of copper obtained very conveniently, and the relative uncertainty is given. It lays a solid foundation to better develop university physics experiment data processing system. |
