电阻的测量,一直是电学实验中的热点。其测量方法有伏安法、半偏法、等效替代法、比较法等,其中伏安法是最基本最常用的方法。伏安法测电表内阻需要结合电表自身的特点,比一般电阻的测量更灵活,它要求根据题给器材,先初步猜想设计出测量电路,然后通过估算,确定可行的实验方案和
Resistance measurement has always been a hot topic in electrical experiments. The measurement methods include voltammetry, semi-partial method, equivalent substitution method, comparison method, etc. Among them, voltammetry is the most basic and most commonly used method. Voltmeter meter internal resistance needs to combine the characteristics of the meter itself, more flexible than the general resistance measurement, it requires that according to the title to the equipment, first guess the design of the measurement circuit, and then through the estimation to determine a feasible experimental program and
