伏安法测量电阻的方法将待测电阻接上直流电源，然后用电压表和电流表分别测量电阻两端的电压和通过电阻的电流，再根据欧姆定律计算出被测电阻。因为测量过程中需要借助电压表和电流表，伏安法是一种间接测量电阻的方法。我们知道，电压表常常并联与电路中使用，电流表常常串联在电路中使用，都是可以带电操作的，故伏安法可以带电进行电阻的测量。伏安法测量电阻的接线方式1）电压表前接电路：适用待测电阻很大（远大于电流表内阻）的情况。

实操过程中同时练习了软件编程和程序上下载、在线修改编辑、在线监控等各项功能。就像“书非借不能读”，花了钱买了硬件，也会促进你的学习欲望，缓解懒惰并发症导致的学业荒废。初学者学习PLC说明一下。1，推荐学习三菱的PLC。三菱的程序是一步一步的。欧美的是一块一块的。当然现在随着融合，好很多了。2，三菱的，西门子的都有仿真软件。下点教程，买两本书看看，编写小程序，感觉一下是否对这个比较热爱。也可以跟别的人，接触过的了解一下。
