### Prerequisites

Basic Differential and Integral Calculus

### Bibliography

1.Fundamentals of Electric Circuits- Charles K. Alexander

### Teaching method

Theoretical-pratical classes and practical/laboratory classes.

Encouragement to study independently through 10 Quizzes throughout the semester.

### Evaluation method

Approval in the Curricular Unit is obtained with a grade equal to or greater than 9.5 Values ​​resulting from a theoretical assessment component (80%), and a practical assessment component (3 reports- 20%). The theoretical assessment component that can be obtained by 2 tests (with weights of 30% each) + 6 Quizzes (20%) or by an appeal exam (80%). Access to the appeal exam is conditioned to students with a positive grade (>=47.5%) in 5 quizzes. The 2nd test has a minimum score of 9.0. The theoretical assessment component must be equal to or greater than 9.5 points.

Update on Update on June 1, 2023- Given the limitations on the availability of moodle (due to the need for updates) verified during the Semester, only 5 quizes will be carried out. positive rating (>=9.50) in 4 quizzes. Access to the appeal exam is conditioned to students with a positive grade (>=47.5%) in 4 quizzes
