伴有电介质的平行板电容器电容的计算分析

Calculation of parallel-plate capacitor with a dielectric

平行板电容器是电磁学课程内容的重要组成部分,关于伴有电介质的平行板电容器电容的求解是学生感到比较棘手的问题之一。本文主要针对平行板电容器内部充有均匀介质或非均匀介质展开分析,根据电容器电容求解的定义式给出了内部充有不同介质时电容的求解结果。

Parallel-plate capacitor is an important part of Electromagnetism, and it is difficult for students to solve the capaci- tance of parallel-plate capacitor with a dielectric. Parallel-plate capacitor with homogeneous or inhomogeneous media was analyzed in this paper and the results about the capacitor with different media were given according to the definition of the capacitor.
