Teaching methods
Classroom lectures are held according to the academic calendar
The course is usually supplemented with three laboratory experiences (mandatory) concerning AC circuits (single phase and three phase), circuits transients and standard tests of transformers
The course is usually supplemented with specialist seminars concerning applied electromagnetism, with particular reference to industrial application of superconductivity
Assessment methods
The exam consists of a written and an oral test. All the didactic support is provided to students during the course. For further information visit http://www.die.ing.unibo.it/pers/negrini/index.htm
