| Abstract: | In this paper,the Cu50 resistance at different temperature has been measured by non-equilibrium bridge at a series of different value of k.With Origin software,the sensitivity of the non-equilibrium bridge and the nonlinear error has been studied.The experiment results are in good agreement with theoretical analysis.The higher of k is,the nonlinear error of the non-equilibrium bridge is smaller and the sensitivity is lower. |
