| 摘 要： | 伏安法测电阻是个经典的电学实验,但由于电表内阻的存在,使得测量电阻时产生一定的误差,可根据测量电阻和电表内阻的大小选择不同测量方法。通过改进伏安法测电阻电路并通过实验与原理的伏安法进行对比,发现改进的方法简便,精度也较高。

| Abstract: | Due to the physical memory of the ammeter internal resistance,it has certain error when masuring resistance with voltammetry which is a classic electrical experiment.Therefore,selecting different methods of measuring according to the amount of ammeter and voltage internal resistance,measuring resistance with voltammetry is convenient after improving its circuit,when ammeter internal resistance is less while voltage internal resistance is larger. |

| Keywords: | voltammetry ammeter internal resistance voltage current |
