Content: sessions will be developed with the initial contents explanation of each lesson of the subject, using multimedia tools. After explaining the content will develop problems and case studies related to such content.

Labs: will be held one hour sessions on the dates indicated in the schedule of the course. During each session will be held, first, the experimental development of the practice on the electrical laboratory and secondly, the simulation will be the practice in the computer lab using Matlab.

Academic activities:

Questionnaire topics: there will be a questionnaire, using an online platform, for each topic of the course on the dates indicated in the schedule of it.
Group work will be a simulation group work in a particular case related to the contents in the subject.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

Content evaluation: written exam (70% of the total score) consists of two different parts. The first part will include an adequate number of theoretical questions and the second part will be held several problems, which are intended to assess the student's acquisition of knowledge developed in the course objectives.

Academic activities evaluation:

Questionnaire topics: the completion of the questionnaires for each of the topics of the course will be assessed with 15% of the overall mark.
Group work: the performance of group work and active participation in the activities developed during the course will be assessed with 15% of the overall mark for the subject.
