Electrical basics course
1st degree and Bachelor-level of the Bologna process in Automotive Engineering - Torino
Objectives of the course
The module will provide the basic electric elements and the main electrical systems. The theoretical aspects are targeted at providing
the operative instruments necessary for solving the practical problems and for understanding the principles of functioning of the most
common electrical devices and systems in the engineering field.
The student must acquire the necessary instruments for the solution of any electrical circuit operating in stationary or almost stationary
systems by means of the different techniques of analysis.
Considered as necessary are the concepts of the Mathematical Analysis I module with particular reference to complex calculus and
algebreic linear system solutions and the Experimental Physics II modules, regarding mainly the themes of electrostatic field, current
field, static magnetic field and the slowly variable fields.

Classroom training is scheduled with exercises and example calculations on the subjects covered in the lesson. Example exercises and
calculations of topics covered in the classroom are also scheduled.
2 workshops with a duration of 4 hours each are scheduled and a guided visit to the Fiat Research Centre (CRF)
1° Workshop (computer): analysis of electrical networks by means of circuit simulation in the PSpice environment
2° Workshop (experimental): realisation and experimental analysis of electrical networks realized in laboratory (LADISPE)
3° Workshop: visit to the testing laboratories of CRF
The teaching staff is available for clarifications of topics covered in the lessons and training. The students are divided into two teams.
