Type of delivery of the course

Frontal lessons oriented to the solution of practical problems starting from problem-based learning. In particular, the lectures and teaching material made available on the university's Moodle platform are aimed at understanding the principles of electrical engineering and their applications, especially in the industrial and domestic fields. The proposed calculation exercises are aimed at developing the ability to solve simple electrical engineering problems such as: choice of components and equipment, sizing of electrical components and systems, preliminary performance calculations, etc.

Attendance

Attendance to lectures and calculation exercises, although not mandatory, is strongly recommended.

Type of evaluation

The final evaluation, expressed with a mark out of thirty, is determined by the results obtained in a written test and an oral test. The written test consists in the numerical resolution of questions related to the different topics addressed by the course such as the resolution of electric circuits in steady state with either direct or alternating current, single-phase or three-phase, the determination of the operating conditions of electric machines subjected to specified load condition, the calculation of the operating conditions of electrical distribution systems. The oral exam consists of an interview in which the different application problems presented in the lectures of the course are discussed.
