摘要

乍一看,本科课程中讲授的一个 RLC 电路的简单模型与实验数据进行了合理的拟合。然而,仔细分析后发现,该模型并不能准确描述电路中的振荡行为,需要进一步完善。测量和分析该系统的数据为高级实验班学生提供了一个机会,使他们能够参与假设构建、建模和实验设计,并设法解释这些数据与模型之间的差异。这项活动的学习成果符合 AAPT 关于本科生实验室经验的指导方针。此外,这种实验还能让学生弥合课堂学习与现实世界之间的差距。

Voltage decay in an RLC circuit is not what is taught: An advanced laboratory exercise
At first glance, a simple model of an RLC circuit taught in undergraduate courses provides a reasonable fit to experimental data. However, careful analysis demonstrates that this model does not accurately describe the behavior of the oscillations in this circuit and requires further refinement. Measuring and analyzing data from this system provides an opportunity for advanced lab students to engage in hypothesis construction, modeling, and experimental design as they seek to explain the discrepancy between these data and a model. The learning outcomes of this activity are consistent with the AAPT guidelines on the undergraduate laboratory experience. Furthermore, such experimentation allows students to bridge the gap between classroom learning and the real world.

期刊介绍: The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.
