摘要
对伏安法作了改进 ,提出等效法测电阻 ,能消除电表内阻的影响 ,无论待测电阻与电表内阻的相对大小如何 ,电流表均可内接或外接 ,待测电阻值由高精度电阻箱之值计算确定 ,而高精度电阻箱精度高 。
This paper brings up a new method of measuring resistance. It can eliminate the effect of resistance inside the ammeter itself. The value of resistance to be measured is calculated by the quantity of high precision resistance box. The measured result is highly accurate.
