    OVERVIEW

    The teaching activity aims at providing the basic tools to analyse DC and AC circuits (single-phase and three-phase), needed, for instance, to carry out a rough sizing of an on-board power system. Furthermore, students will acquire a basic knowledge of electronic components (transistors, operational amplifiers) and logic networks, as well as electrical machines and generation and storage systems, with emphasis on power and energy balances.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    Provide basic theoretical knowledge of electrical engineering and electronics : the behavior of an electrical circuit direct and alternating current, transient and steady state ; measurements of certain electrical quantities ; operation of electrical and electronic components of some machines ; combinatorial logic networks ; electricity balance ; systems and schemes .

    AIMS AND LEARNING OUTCOMES

    At the end of the teaching activity, students will be able to analyse:

    - DC circuits
    - AC circuits
    - simple transients

    employing both systematic methods (nodal and mesh analysis) and by simplifying the circuit by means of Thévenin and Norton theorems, Millman formulas, etc.

    Students will also acquire a basic knowledge of:
    - electronic devices and amplifiers
    - electrical machines
    - power systems

    Students will be able to analyse simple circuits with BJTs and operational amplifiers, to use Karnaugh maps for logic circuits synthesis, to perform power and energy balances.

    TEACHING METHODS

    Both for the first and the second part, the lessons will alternate theory and exercises or application examples.

    The presented exercises and application examples are of the same kind of those the students will have to solve during the exam.

    EXAMS

    EXAM DESCRIPTION

    Oral exam: discussion of about half an hour.

    The test will consist of three questions: 

    - a subject chosen by the student, on one of the topics presented during the teaching activity
    - a question about circuit theory
    - a question about electronics, logic networks, power generation and storage.

    The questions focus both on the theoretical arguments presented during the teaching activity and on simple exercises similar to those presented during the same activity.

    ASSESSMENT METHODS

    The chosen topic will be evaluated on the basis of the property and level of understanding of the subject shown by the student.

    As far as the second and third questions, the student will have to demonstrate the ability of solving simple exercises similar to those presented during the lessons (for example, solution of simple DC or AC circuits, analysis of networks with operational amplifiers and BJTs, logic network synthesis) and the ability of discussing  theoretical aspects covered during the lessons (for instance: circuit laws, network theorems, solution methods, phasor method, etc...), as well as explaining the meaning of the main quantities addressed during the teaching activity (such as currents, voltages, DC and AC powers,, characteristics of the bipoles, etc...).
