摘要
在农村和城市教育环境中，科学教学常因实验资源有限和令人 intimidating 的复杂仪器而受到阻碍。本文介绍了一种低成本、手工制作的实验装置，利用移动充电器、镀锆丝、电流计和数字万用表即可实现关键的高等 secondary 电力实验。原产民仪表桥（Indigenous Metre Bridge, IMB）已被证明是一种直观易用的工具，不仅能搭桥理论与实践学习，还能降低学生对实验工作的恐惧感。其简单性和可及性体现了 frugal innovation 如何改变物理教育的潜力。

备注
The manuscript is approximately 8 pages long and includes 6 figures (experimental setup diagrams, graphs, and circuit illustrations) and 1 table presenting Ohm's law verification data. The figures are clear and pedagogically useful, especially Fig. 1 (IMB setup) and Fig. 3 (Ohm's law graph), while the table effectively supports the experimental results
