Lessons are available on Virtuale Unibo. This material is exhaustive for the comprehension of the course. Recommended books are

-‘Electric circuits’ Charles K. Alexander, Matthew N. O. Sadiku and

-‘Electrotechnics: Principals and Applications’ G. Rizzoni.

-'Elettrotecnica: elementi di teoria ed esercizi' di M. Repetto e S. Leva

- 'Elettrotecnica 1 e 2' di G. Chitarin, F. Gnesotto, M. Guarnieri, A. Machio, A. Stella

Teaching methods

The 30 hours of frontal teaching include the theoretical part of the course and the exercises suitable for the in-depth study of electrical and magnetic circuits

Assessment methods

Verification of learning takes place through a final exam that ascertains the acquisition of the knowledge and skills expected by carrying out a written test lasting 1 hour and a half.

The test usually consists in the resolution of 1 exercise in which it is required to study an electrical circuit in steady state regime, and in an open question relating to theoretical aspects.

The grade of the exercise will weigh 2/3 of the final grade, the theoretical question 1/3.

Passing the exam will be guaranteed to students who demonstrate mastery and operational ability in relation to the key concepts illustrated in the teaching, and in particular in relation to the fundamental concepts of electromagnetism and the ability to solve electrical and magnetic circuits. A higher score will be attributed to students who will demonstrate that they understand and are able to use and connect all the teaching contents. Failure to pass the exam may be due to insufficient knowledge of the key concepts.
