关于欧姆计的最佳分辨角求证

Seeking to Prove the Accurate Angle Range of Ohmmeter

从全电路欧姆定律出发 ,对欧姆计量程中段的精确测量范围作出了定量的分析和证明 :如果欧姆计的满量程偏转角度为 90° ,则其中间的精确测量范围约为 46°。

According to the Ohm's law of the whole circuit, a quantifing analysis and proof to the accurate central on Ohmmeter is achieved. The result points out that if the meter full scale is 90°, the accurate angle range is about 46°.
