General description and relevant information <div><p>GENERAL DESCRIPTION OF THE SUBJECT:This course is the natural continuation of Circuit Theory I. It starts with the analysis of balanced and unbalanced three phase circuits. Next, it address the analysis and synthesis of networks: time and frequency responses of linear circuits, circuits in the Laplace domain. Finally, it offers basic concepts of two-port networks.</p><p>Note: In case of discrepancies between this English version and the Catalan version, the information that prevails is the one in the Catalan version of the subject.</p></div>

Methodologies
Methodologies
  Description
Introductory activities Presentation of the subject at the regular classroom.
Laboratory kick off: groups, workbench assignation, necessary material.
Lecture Presentation of the contents of the subject.
Theory interspersed with meaningful examples.
Problem solving, exercises Face-to-face: Solving problems, test questions, examples of partial tests and students' doubts.
On-line: the Virtual Campus offers varied exercises to practice.
Laboratory practicals Mandatory Pre-Study before each lab session that must be submitted to moodle and evaluated.
Mandatory laboratory attendance sessions (usually in two-person teams) where both team work and individual active participation are taken into account.
A report is drawn up with the results obtained. The ability to apply the methods and procedures for carrying out the measurements, the ability to interpret the results in accordance with theoretical knowledge and foundations, and written expression are assessed.
Personal attention Individual attention or in small groups in the teachers' office and/or in the Virtual Campus forum. Email attention is also offered.

Personalized attention
Description

Professors' office hours to solve students’ doubts. Due to the health emergency, online meetings can be appointed by email from student addresses "name.surname@estudiants.urv.cat". Other online contact procedures such as sharing questions and answers at the Virtual Campus forums, where students can interact under the professors supervision, are also available. In addition to individual meetings, small groups sessions can also be appointed.

Other comments and second exam session

To pass the subject, it is necessary to obtain a minimum of 3,5/10 in the global laboratory practices, a minimum of 3.5/10 in the joint qualification of the partial exams, and a weighted average (global practices and global exams) greater than or equal to 5/10. It is mandatory to do all the practices and partial exams. Although the teaching language of the different groups specified in the teaching guide may be different, statements of tests, practices and problems will be provided only in Catalan.

The global laboratory practice grade has a weight of 30% in both calls. In order to assess the final grade of the practices, individual additional exams can be carried out.

The second call will consist of an exam (test and/or problems) of the entire syllabus with a weight of 70%. There will be no specific evaluation of laboratory practices in the second call because the laboratory practices must be carried out during the continuous evaluation period.

Normally, the exams will be held face-to-face. During them, students will not be authorized to use any communication and data transmission device unless they receive express instructions from the supervising professors allowing their use.

In order to verify the identity of the students, to guarantee their evaluation rights, and to provide them with the necessary support, both online exams and online personalized attention may require the remote viewing of images provided by the communication devices used. The students must notify the people they live with of such circumstances and recommend that they not enter their surroundings during exams and consultations. In any case, the URV is not responsible for the accidental viewing of images that may affect the private and family life of the student. The student is not allowed to capture images without express authorization. If the professors deem it appropriate, they may ask students to show an identification document to prove their identity.
