Learning objectives
Industrial Application of Electric Systems
This course aims at providing to non-electrical student basic knowledge of electric circuits, electromechanical systems and of their applications, in order to enhance the core technical background of a future engineer.
Prerequisites
The students are expected to be familiar with the notions of mathematics and physics taught in the 1st and 2nd year of the Laurea in Mechanical Engineering.
