Methodology

The Electric Circuits course uses a theoretical-practical approach, combining master classes, problem classes, activities and group work, laboratory sessions and autonomous learning by the student.

The lectures will consist on the theoretical explanation of the fundamental aspects of each topic, as well as the resolution of questions raised by the students from their autonomous learning of each topic. As part of the practical, individual and / or group activities, practical exercises and works related to the topics covered will be carried out.

To understand the subject and obtain an adequate outcome, it will be necessary for the student to carry out continuous work around the following activities:

• Attend class regularly.
• Carry out a reflective reading and an in-depth study of the material that is provided or indicated in each topic.
• Solve the exercises and work proposed throughout the course.
• Actively participate in discussions that may arise in class.
• Asking questions that may arising during the study of the subject in the hours arranged by the teacher for this purpose.

As a teaching complement, MiAulario will be used. Through it, the calendar of the different activities of the subject will be indicated, it will be possible to access the teaching material and it will be used to send the works requested in class.

Evaluation

NOTE: A minimum mark 5/10 is required in the average of the 3 exams (A minimum mark is not required in any of the exams). Laboratory sessions will not be weighted with a mark lower than 5 in the average of the exams, being the final mark the average of the exams. All the exams of the continuous assesment are recoverable but in a single exam (second-chance exam).
