The 2 ECTS section of physics included in this course is an introduction to electromagnetism. After finishing this section the student understands the concepts of electric field, potential and voltage and will be able to apply these concepts in the calculation of simple DC circuits. The student knows the operation principles of a resistor, a capacitor and voltage supply as electrical circuit components. In addition, the student understands the concept of magnetic field and is able to apply magnetic force influence on a conductor or a current loop in a magnetic field. Based on these concepts the student understands the concept of electromagnetic induction and the operation principles of an electrical motor and generator.

After completing the 3 ECTS section of electrical engineering the student is able to make simple AC circuit analysis calculations. The student knows the basics of the electrical safety and is able to operate electrical equipment safely. The student knows the operation principle of the transformer as well as the most common electrical motor types. The student knows the main criteria for electrical device rating and is able to select protective devices for an electrical drive.
