Abstract
Circuit experiment is a very important professional basic course for students of electrical experiments. Experiment study is further validation of theoretical study and supplement. If the deviation between the experimental data and the theoretical value is large, it will not verify the theoretical value, instead it will make students feel puzzled. So if there is a problem, how to solve it? This paper is mainly from the experiment, numerical simulation and theoretical values to compare and determine the accuracy of measuring damping coefficient method under the condition of under-damped RLC second-order circuit. It also analyzes the reasons of the error, and then put forward the damping coefficient correction method.
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.
