01MBMJA Electric circuits I 

Corso di Laurea in Electronic And Computer Engineering  Vercelli 





Obiettivi dell'insegnamento
The general methodologies for the analysis of electrical circuits are presented. The teaching strategy is based on the use of induction and on examples: active participation and interaction is expected during the lectures, since the theoretical parts are complemented by many practical examples that should be solved by the students during collaborative group exercises.

Competenze attese
The student should acquire the capability of manually solving simple circuits by hand calculations, and more complex circuits with the aid of a circuit simulator. Expected skills include general analysis methods of electric circuits under constant, sinusoidal, and arbitrary excitations The course material is essential for a basic understanding of the electronic applications that will be encountered by the student in successive courses.

Prerequisiti
Calculus I and II, Electromagnetiscm and Optics, Linear Algebra.

Programma
Voltage, current, power. Kirchhoff laws. Basic circuit elements: resistors and ideal voltage and current sources. Series and parallel connections. Nodal analysis. Millmann's Theorem. Linearity and Superposition. Thevenin's and Norton's theorems. Dependent sources. Operational amplifiers. Diodes. Operating point and differential resistance. Capacitors and inductors. Firstorder circuits. Secondorder circuits. Sinusoids and phasors. Impedance and admittance. Sinusoidal steadystate analysis. AC power analysis. Laplace transform and its application to general circuit analysis. Network functions and their properties. Twoport and multiport networks

Laboratori e/o esercitazioni
The entire course program is the subject of several inclass group exercise sessions. A few computer lab hours are dedicated to the circuit simulator SPICE. Weekly sessions will be organized for group exercises under the supervision of a tutor.

Controlli dell'apprendimento / Modalità d'esame
The exam is structured in a written test (two hours) followed by an oral test. The written part includes both elementary tests and more complex circuits to be solved manually. No consultation of textbooks or notes is allowed during the written test. A positive score on the written test allows access to the oral test, aimed at the indepth verification of the competencies acquired by the student.
