TEACHING MATERIALS  AULAWEB 
This subject aims to provide basic elements of electrical circuit theory (resistive elements and networks, transient and steadystate analysis of elementary firstorder and secondorder linear circuits, analysis of some circuit properties in periodical steadystate conditions) and to apply them to examples. To this end, concepts coming from Mathematics, Physics and Geometry are applied to circuits and some basic mathematical and scientific principles are introduced.
To be able to analyse a linear timeinvariant circuit (transitory and steadystate analysis).
It is expected that at the end of this subject the student will be able to analyze linear timeinvariant resistive circuits and firstorder and secondorder dynamical circuits (transitory and steadystate 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 nontrivial problems is one of the main elements of the scientific cultural baggage of an engineer.
Basic concepts of mathematics and physics: derivatives and integrals of real functions; elementary linear differential equations; vectors, matrices, systems of algebraic equations; complex numbers; power and energy.
About 60 classroom hours, taken remotely, through Teams platform. During other practice lessons (with elective participation), further exercises and examples are proposed, by resorting to teambased learning and flipped classroom.
Fundamentals of circuit theory (circuit elements; models; elementary electrical variables; graphs and circuits; Kirchhoff's laws; Tellegen's theorem).
Twoterminal resistive elements and elementary circuits (significant twoterminal elements; ThéveninNorton models; concept of electrical power; series and parallel connections).
Linear resistive twoports and elementary circuits (six representations and properties; significant twoport elements; cascade, series and parallel connections).
General resistive circuits (Tableau analysis; superposition and substitution theorems; ThéveninNorton theorems).
Elementary dynamical circuits (significant circuit elements; concept of state; transient and stationary steadystate solutions of firstorder circuits with various sources: constant, piecewiseconstant, impulsive; stability; generalizations to second and higherorder circuits).
Sinusoidal steadystate analysis (phasors and sinusoidal solutions; phasor formulations of circuit equations; impedance and admittance of twoterminal elements; sinusoidal steadystate solutions; active, reactive and complex powers).
Periodical steadystate analysis (analysis of circuits with many sinusoidal inputs; periodical signals and Fourier series; mean value; RMS value theorem).

Common score:
The teacher will propose exercises for selfassessment at the end of each topic. Some of these exercises will be studied and solved by small groups of students under the supervision of a tutor (teambased learning). Each student (individually) will solve publicly a part of these exercises during classes (flipped classroom), thus obtaining a max. score of 2.
“Facetoface” mode:
Written (max. score 17, with threshold of 4 for being admitted to the oral exam) + oral (max score 15).
With higher priority for those that are first registered in the official University list of students of this subject: two partial written examinations, one towards half semester and one just after the end of the semester (max. score 32). Threshold score of the first examination: 3 (out of about 12). If the overall score is sufficient (>= 18), it can be the final score of this subject. Otherwise, a further oral examination (max. score 30) will contribute to the final assessment, by averaging written score and oral score.
“Distance” mode (only if necessary, according to national and university rules):
Preliminary assessment test (max. score 7), with threshold score of about 3 (it can change based on the difficulty level of the test) + written assessment (max. score 10) + oral assessment (max. score 15). For being admitted to the oral examination, the student must have min. score 5 (preliminary test + written assessment). The final score is given by test + written + oral + flipped classroom.
Students with learning disorders ("disturbi specifici di apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a casebycase basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.
For the oral examinations (including flipped classroom interventions), the assessment will be based on:
) communication skills
) knowledge and comprehension of the subject topics
) ability of drawing connections among ideas
For the written examinations, the assessment will be based on:
) ability of analyzing circuits, by correctly writing topological equations and descriptive equations
) ability of deciding what subset of tools can be (or must be) used to solve a given circuit problem (i.e., of using information in partially new situations) and of justifying each decision
