The course is organized into lectures and practical classes. Practical classes (approximately 30% of each credit) are aimed at applying the circuit analysis methods presented during the lectures. During the teaching period, students will be asked to periodically perform online self-evaluation tests. At the end of the course, a total score of maximum 6 points will be assigned to each student, based on the results of these tests.

Written test (18/30 points). The written test is divided in two parts. 1) Elementary questions about the course fundamental topics (6/18 points): students are asked to analyze simple electrical circuits (without providing numerical derivations) or to answer theoretical questions. Students that performed all the periodical self-evaluation tests, and reached a minimum score of 4/6, are allowed to skip this first part of the written exam. 2) Numerical solution of an electrical network (12/18 points): students are asked to solve numerically more involved electrical networks. For this second part, students must provide the full derivations that lead to the circuit solution. Oral test (12/30 points). The oral test starts by discussing the results of the written tests. Then, the student will be asked to answer questions about the topics covered during the course lectures.

The final exam consists of a written test composed by exercises and theoretical questions. The exam lasts two hours. During the exam you cannot consult any material. The score obtained from the written exam is summed with the evaluation of laboratory exercises. The resulting score can be integrated (-3 to +3) with an optional oral session. The oral exam can be related to any part of the course, including the laboratory experiences.
