低值电阻测量中电压接头内外接法的等效性研究

Study on the Equivalent of the Voltage Jointer linked Inside and Outside in Measuring Low Resistance

低值电阻的测量中 ,传统方法是采用电压接头内接法而排斥外接法 .本文依据电路分析得出了电压接头内外接法的等效性结论 。

Traditionally, measuring low resistance with the voltage jointers has been made by being linked inside rather than outside. In this paper, the analysis is made for the equivalent of the voltage jointer linked inside and outside according to the circuit. The equivalent is also proved by the experimental result.
