## AIMS AND CONTENT

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, taken remotely, through Teams platform. During other practice lessons (with elective participation), further exercises and examples are proposed.

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).

Periodical steady-state analysis (analysis of circuits with many sinusoidal inputs; periodical signals and Fourier series; mean value; RMS value theorem).

EXAM DESCRIPTION

“Face-to-face” mode:

Written (max. score 19, with threshold of 4 for being admitted to the oral exam) + oral (max score 15).

Reserved to the students 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 34). Threshold score of the first examination: 3 (out of about 12). If the overall score is sufficient (greater than or equal to 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:

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.

ASSESSMENT METHODS

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
