This article presents a simulation test for the time constant of an RC circuit in college physics experiments using Multisim software. The author analyzes the relationship between the time constant and the ratio of capacitor voltage during charging and discharging processes. Several experimental schemes for measuring the time constant are proposed, which can intuitively demonstrate the working process of the RC circuit and related parameters. This approach facilitates the integration, application, and transfer of knowledge, enhancing the flexibility and visibility of electrical analysis.

The article is recommended for readers who are interested in the application of simulation technology in physical experiments. It provides a practical example of how Multisim can be used to simulate and test electrical circuits, making complex concepts easier to understand. The simulation test described in this paper can be easily implemented in college physics laboratories, providing students with a more engaging and visual learning experience.

The simulation test presented in this article is based on the latest version of Multisim software and covers various experimental methods for measuring the time constant of an RC circuit. The theoretical calculations and simulations are in good agreement, demonstrating the accuracy and effectiveness of the proposed method.

In conclusion, this article offers a valuable resource for those looking to integrate simulation technology into their college physics experiments. The use of Multisim software in this study has shown to be beneficial in enhancing teaching effectiveness and promoting student learning. The simulation test described in this paper is a practical and effective method for measuring the time constant of an RC circuit, providing students with a better understanding of electrical circuit principles.
