UJ31型电位差计实验设备的改进
Improvement of Potentiometer Experimental Equipment of UJ31
摘要
Abstract
Using the compensation method principle,the potentiometer is used to precisely measure the electromotive force,electrical quantities such as voltage,current and resistance.During the actual teaching process,the test error of result is bigger because of the use of accessory equipment mechanical galvanometer cannot grasp well when students use the type UJ31 potential difference.The result is better when the attachment equipment mechanical galvanometer substitute digital instrument by discussion and demonstrate.关键词
