OVERVIEW

The course is divided into lectures and laboratory exercises designed to teach the student to make simple breadboard circuits and to correctly connect instruments such as voltmeter, ammeter, voltage generator and digital oscilloscope.

AIMS AND CONTENT

LEARNING OUTCOMES

The course offers students specific electrical engineering elements and focuses on theoretical and practical bases for components and materials, with the support of laboratory experiences conducted by the students themselves.

AIMS AND LEARNING OUTCOMES

The student will acquire knowledge on the fundamental properties of materials, with particular regard to electrical properties. Conductive, insulating, semiconductor and magnetic materials used in the construction of machines and electrical equipment will be introduced: the main parameters that characterize them, the relative units of measurement and the laboratory techniques used to determine them will be defined.

TEACHING METHODS

Lectures, practical exercises in the laboratory.

SYLLABUS/CONTENT

The course is divided into lectures and laboratory exercises.

Summary of the topics covered in the theoretical part:

The teacher presents the fundamental properties of materials with particular regard to electrical properties. We examine the conductive, insulating, semiconductor materials used in the construction of machines and electrical equipment: we define the main parameters that characterize them and the main laboratory techniques used to determine them.

In particular, we introduce the first and second Ohm's law, we define the dependence of the electrical Resistivity on temperature in the case of metallic conductors. The linear and non-linear voltage-current curve is considered. The Law of Joule is presented in integral and local form.

As far as Dielectric materials are concerned, homogeneous materials and composite materials are considered: references are made to the expression of the electric field with simple electrode geometries. The fundamental parameters of a capacitor are introduced and the direct current RC circuit is analyzed from a theoretical point of view. From the continuous regime, we then move on to the sinusoidal regime: the concept of phasor is introduced, to be able to define capacitor and inductor impedances and reactances, and the concept of skin effect.

Laboratory exercises:

The students, divided into groups and under the supervision of the teacher, carry out the following practical exercises: Series and parallel resistances, Ohm's first law, Voltage-current curve of a low voltage incandescent bulb and a diode, RC circuits in direct current, passive RC filters in sinusoidal regime at different frequencies.

The objective of the exercises is to learn how to make simple breadboard circuits, how to correctly connect instruments such as voltmeter, ammeter, DC voltage generator, function generator and digital oscilloscope.
