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.
Frontal lectures in classroom. During other practice lessons (with elective participation), further exercises and examples are proposed.
Working students and students with disabilities or learning disorders (e.g., DSA) are advised to contact the teacher at the beginning of the course to discuss about teaching and exam methods.
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).

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.
For the oral examinations, 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
