Experimental research on Measuring amperemeter inner resistance by "Wheaststone bridge-Substituting" method
Tao Li · Journal of Guiyang University · 2013
The principles of combining traditional Wheaststone bridge method with traditional substituting method in measuring amperemeter inner resistance is introduced,compairing this method with voltmeter-ammeter and digital multimeter in experiment,it is analysed and proved through experimental data that the method of connecting Wheaststone bridge with substituting is more accurate.
