The teaching aims at providing to the students the basic notions of electric circuit theory. Classical topics (elementary analysis of linear circuits in DC and AC steady state and in transient) are studied and proposed to the students in order to familiarize with the tools from mathematics, geometry and physics necessary for the circuit analysis.
Fundamental notions of electric circuit theory. Analysis of linear circuits in DC and AC steady state and in transient. The studied topics are proposed to the students in order to familiarize with the tools from mathematics, geometry and physics necessary for the circuit analysis.
At the end of the teaching the student will be able to analyze a linear, time-invariant circuit in transient and steady state (DC and AC).
Linear algebra, linear ordinary differential equations with constant coefficients, complex numbers.
Classroom lessons. Optional lessons are also planned, where exercises are solved in preparation for the exam.
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). Exercises and examples.

Written (max. score 19) + oral (max score 15). During the course, many exercises will be proposed to the students for self-examination. For the attending students, two further partial written examinations will be proposed, with a total score of 34: if the total score is sufficient, it can be registered without any additional oral examination; otherwise, an oral examination (max. score 30) is mandatory and the final score is the mean of written and oral examination.
The written exam verifies the ability of analyzing linear, time-invariant circuits and obtaining the transient and steady state (DC or AC) solution.
The oral exam verifies the comprehension of the theoretical notions necessary to study linear circuits.
