Subject fundamentals
The main objective of the course is to introduce students to the basic laws governing lumped electrical circuits. It provides the essential background required to fruitfully attend the electronic courses and to understand the recent key electrical and electronic applications. In particular the course focuses on the fundamental tools to analyze resistive circuits and dynamic circuits operating in the sinusoidal steady-state and to compute the transient response of first- and second-order circuits.
Expected learning outcomes
Knowledge of the constitutive relations governing the basic circuit elements (RLCM). Knowledge of the different techniques for circuit analysis along with their key features, strengths and limitations. Ability to analyze electric circuits, choosing the most convenient techniques. Specifically, knowledge of the inspection method for the analysis of the transient response of first- and second-order circuits and of the phasor method for the analysis of circuits operating in the sinusoidal steady-state. The students will be ready to compute the voltage-current constitutive relation of any two-terminal element that consists of the interconnection of basic two-terminal elements, to solve simple direct- and alternate-current electrical circuits with RLCM components and to compute the transient response of first- and second-order circuits. The practice sessions will help students to improve their problem-solving skill, allowing them to exchange their experience on the selection of the best possible solution method for the different classes of application problems.

Assessment and grading criteria
The knowledge, and the ability to apply it, will be verified during the final examination, which is structured in a written test (duration 90 min). The exam includes 5 elementary problems (4 points each, total 20 points) and one or two more complex circuits (12 points total). During the written test, it is possible to use a scientific calculator; no texts, books and notes are admitted. An optional short oral test is allowed for students obtaining the maximum score in the written exam to reach the grade 30L.
