摘　　要：伏安法测电阻作为一个基本的电学实验,既包含了欧姆定律也包含了电路连接知识,准确测量电阻的伏安特性参数是对伏安法测电阻的基本要求。通过分析伏安法测电阻内接法与外接法的原理,讨论电路和元器件的选择带来的误差原因,从而找到在电路中接入不同的电表来减小误差的方法。Voltammetry is a basic electrical experiment.It includes both Ohm's law and circuit connection knowledge.Measuring voltammetry characteristics of resistance accurately is the basic requirement of voltammetry.This article analyzes voltammetry in theory and discuss the systematic errors when applying the inner and out connecting methods.Finally,it gives the more reasonable method to eliminate systematic errors by choosing different ammeter and volmeter.
