OVERVIEW

The teaching unit aims to provide fundamental knowledge of electrical circuit theory. The topics covered are classical (resistive components and circuits, analysis of linear dynamic circuits under steady-state, sinusoidal or periodic conditions, and in transients) and are presented in a way that allows students to become familiar both with the mathematical, physical, and geometrical tools essential for circuit analysis and with the mathematical and scientific principles underlying engineering.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the basic knowldge to analyze linear time-invariant circuits (transitory and steady-state analysis), by using the fundamental tools of the circuit theory. Moreover, the course provides knowledge to use the tools of mathematics, physics, and geometry indispensable in the analysis of circuits.

AIMS AND LEARNING OUTCOMES

It is expected that at the end of this subject the student will be able to analyze linear time-invariant resistive circuits and first-order and second-order dynamical circuits (transitory and steady-state analysis), by correctly writing topological equations and descriptive equations. During the lessons a set of tools are proposed; when dealing with a specific problem, the students have to decide what subset of tools can be (or has to be) used to solve it. This capacity of solving non-trivial problems is one of the main elements of the scientific cultural baggage of an engineer.

TEACHING METHODS

About 60 classroom hours. During other practice lessons (with elective participation), further exercises and examples are proposed to reinforce learning.
Attendance at lectures and exercises is strongly recommended.
Working students and students with certified specific learning disorders (SLD), disabilities, or other special educational needs are encouraged to contact the instructor at the beginning of the course to agree on teaching and assessment methods that, while respecting the learning objectives, take into account individual learning styles

SYLLABUS/CONTENT

Fundamentals of circuit theory (circuit elements; models; elementary electrical variables; graphs and circuits; Kirchhoff's laws; Tellegen's theorem).

Two-terminal resistive elements and elementary circuits (significant two-terminal elements; Thévenin-Norton models; concept of electrical power; series and parallel connections).

Linear resistive two-ports and elementary circuits (six representations and properties; significant two-port elements; cascade, series and parallel connections).

General resistive circuits (Tableau analysis; superposition and substitution theorems; Thévenin-Norton theorems).

Elementary dynamical circuits (significant circuit elements; concept of state; transient and stationary steady-state solutions of first-order circuits with various sources: constant, piecewise-constant, impulsive; stability; generalizations to second- and higher-order circuits).

Sinusoidal steady-state analysis (phasors and sinusoidal solutions; phasor formulations of circuit equations; impedance and admittance of two-terminal elements; sinusoidal steady-state solutions; active, reactive and complex powers).

EXAMS

EXAM DESCRIPTION

Written + oral.

Threshold score of the written exam: 6 (out of 20). The oral exam is a discussion of the written exam, in which the candidate must demonstrate a mastery of the subject matter. No proofs are requested in this phase. The oral exam can increase (up to +10) or decrease the score of the written exam.

If the overall score is sufficient (>= 18) and satisfactory for the candidate, it can be the final score of this subject. Otherwise, a further oral examination (max. score 30, proofs are requested in this phase) will contribute to the final assessment, by averaging written score and oral score.

Students with disabilities or specific learning disorders (SLD) are reminded that, in order to request accommodations for exams, they must first upload their certification to the University website at servizionline.unige.it in the "Studenti" section.
The documentation will be verified by the University’s Office for the Inclusion of Students with Disabilities and SLD: https://rubrica.unige.it/strutture/struttura/100111.

Subsequently, students must send an email to the instructor responsible for the exam at least 10 days in advance of the exam date, copying both the School's Inclusion Contact Person for students with disabilities and SLD, and the above-mentioned Office.
The email must include the following information:

- the name of the teaching module

- the exam date

- the student's full name and student ID number

- the compensatory tools and dispensatory measures considered necessary and requested

The Inclusion Contact Person will confirm to the instructor that the student is entitled to request accommodations and that such accommodations must be discussed and agreed upon with the instructor. The instructor will then confirm whether the requested accommodations can be granted.

Requests must be submitted at least 10 days before the exam date, to allow the instructor sufficient time to evaluate them. In particular, if the use of concept maps is requested for the exam (which must be significantly more concise than those used during study), failure to meet the deadline may result in insufficient time to make any necessary revisions.

For further information on requesting services and accommodations, please refer to the document: Guidelines for requesting services, compensatory tools and/or dispensatory measures, and specific aids.

ASSESSMENT METHODS

During the lessons, many exercises are proposed to the students for self-examination and later solved during the optional practice lessons. The learning results are assessed through the exams, as described in the above section. The learning outcomes are reached as far as the student demonstrates his/her ability to properly use the conceptual tools proposed during the lessons, in order to analyze different kinds of circuits working under different operating conditions (see Section "Aims and learning outcomes").
