Obiettivi dell'insegnamento
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.
Competenze attese
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.
Prerequisiti
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.
