Study Guide

Teaching methods

After having passed the first part of the course (2 ECTS), the student understands the kinematics and dynamics of a rigid body in rotational motion. He/she masters the determination of the moment of the inertia by using tables and applying Steiner's rule. 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.

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.
