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.
期刊介绍:
"Experiment Science and Technology" is a comprehensive journal of natural sciences and engineering sponsored by the Sichuan Provincial Department of Education and the University of Electronic Science and Technology of China and the Sichuan Higher Education Association. It aims to report the development status, achievements or interim achievements of scientific research in natural sciences with talent training as the center; exchange research results and experience in the design, development, function development, maintenance management and supply management of instruments and technical equipment; explore common problems in the construction of laboratories at all levels and types, team building and improving the efficiency of instrument use from a technical perspective; explore new ideas, new ways and new measures for experimental teaching reform and innovation.
The journal mainly has columns such as experimental technology, experimental teaching and teaching experiments, virtual simulation technology, laboratory environment and safety, experimental instrument development and maintenance, laboratory construction and management, and large-scale instrument management and sharing.
