对于许多技术实例，对麦克斯韦方程全集的低频近似是适用的。通常，位移电流密度或感应电流密度被忽略，这取决于对特定问题设置的主导效应的先验知识。这导致了麦克斯韦方程的不同子集，分别描述了电感-电阻或电容-电阻系统。本文提出了一种结合两种情况的公式，同时保持准静态假设，即不对波的传播和辐射进行建模。该公式被应用于一个简单的测试模型，该模型由嵌在介质绝缘中的有界大质量导体组成。
For many technical examples, low-frequency approximations to the full set of the Maxwell equations are applicable. Commonly, either the displacement current density or the induced current density are neglected depending on a priori knowledge about the dominating effects for a specific problem setup. This leads to different subsets of the Maxwell equations describing inductive-resistive or capacitive-resistive systems, respectively. In this paper, a formulation combining both scenarios while maintaining the quasistationary assumption, i.e., without modeling wave propagation and radiation, is presented. The formulation is applied to a simple test model consisting of a bounded massive conductor embedded in a dielectric insulation.
