OVERVIEW

The teaching unit aims to provide fundamental knowledge of electric circuit theory. The topics covered are classical (components and resistive circuits, analysis of linear dynamical circuits in DC/AC steady-state, and in transient) and are presented in a way that allows students to gain familiarity with mathematical, physical, and geometrical tools essential for circuit analysis, as well as with the mathematical and scientific principles underlying engineering.

AIMS AND CONTENT

LEARNING OUTCOMES

This course provides the student with the ability 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.

AIMS AND LEARNING OUTCOMES

By the end of the teaching unit, students will understand the characteristics of the main electrical components. They will be able to correctly apply descriptive and topological equations to analyze linear time-invariant circuits in transient, and DC/AC steady state.

PREREQUISITES

Basic knowledge in the fields of mathematical analysis and physics: derivatives and integrals of real functions, vectors, matrices, and systems of algebraic equations; linear differential equations with constant coefficients; complex numbers and their main properties; concepts of power, work, and energy.

TEACHING METHODS

Lectures delivered by the teacher in class.

During the lectures, in addition to theoretical explanations, the theacher will solve numerous exercises related to circuit analysis.

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.
