Course detail
Fundamentals of Electrical Engineering
FCH-BC_ZETAcad. year: 2024/2025
The subject is focused on the basics of electrical and electronic circuits, principles of sensors of non-electrical quantities, measuring systems, drives of electrical machines, to the extent necessary for undergraduate students of the Faculty of Chemistry. Attention is also paid to issues of occupational safety and current legislation. Emphasis is placed on laboratory exercises, where the student will practically try out the knowledge gained from the lectured material.

Entry knowledge
The student should have the basics of physics and the measurement of physical quantities.
Rules for evaluation and completion of the course
Oral examination (70%), which is preceded by a written test to be satisfied at 60%.
Active participation in the lessons, including passed test (30%).
Aims
The course will provide students with a basic overview of electrotechnical elements in industry and automation. The interpretation will be linked at appropriate places with the issue of materials in electrical engineering. The goal is to understand the principles and limits of measuring non-electric quantities, the principles of controlling the electrical power of equipment, PID regulation, the principles of digital technology and communication, and methods of securing and protecting against electric shock.
