Learning Outcomes
Following course completion, the students will be capable of comprehend and get familiar with the physical quantities, properties and methods of the electrostatic field, the steady state current flow field, as well as the behavior of materials in their presence, based on the macroscopic model of classical electromagnetism. More specifically, the students will acquire the following skills: - To understand the physical meaning of various physical quantities and concepts in various practical and applied problems of the electrostatic field, the steady state current flow fields and describe the form of fields, charges and currents in respective systems. - To perform simple calculations of the electrostatic field in simple, model components consisting of conductors and dielectrics, thus approximating more complex problems of current technological practice. - To perform energy and power calculations in simple structures and components under the influence of the electrostatic field. - To use specialized electromagnetic analysis software for static fields to model complex devices and components.
