Learning outcomes:
After successfully completing this module, students will be familiar with the basic electrotechnical knowledge and analysis methods from the field of direct current theory and the electrical field required for all areas of specialization offered in the program. This means that they will be able to calculate with the relevant physical formulas and quantities and, based on the generally valid, common physical-mathematical laws, derive or implement useful approaches and calculations for problems arising from this subject area.
They will be familiar with the analogies between the flow and E-fields and the properties of materials, as well as the mutual interactions between the fields and materials. In particular, they will be able to determine the field characteristics of both fields for frequently occurring geometries and how they are fundamentally influenced by shapes and materials. They will be able to:
- calculate - (also for inhomogeneous fields or fields of several sources) - field and potential energy curves, forces on charges / electrodes / interfaces, as well as energies
- carry out circuit and component calculations and designs using various common analysis methods for circuits with linear components (EQV, MSV, KPV) and non-linear components (operating point determination)
- calculate dynamic processes in RC circuits
With this knowledge, students will be able to perform computational and metrological analyses, as well as configurations even on unfamiliar simple circuits or new problems. They will also be able to dimension components.
Through a series of experiments in the lab course, which are designed as small projects and carried out in small groups, the students will have acquired skills in teamwork, time management and working independently.
