Competencies / Learning Outcomes

Specific skills

  • S17. Systematically analyze the behavior of electrical circuits, identifying the particular operating characteristics of direct current, alternating current and transient regimes.

  • S18. Apply the principles of circuit theory and electrical machines to engineering problems.

  • S24. Design analog, digital and power electronic circuits.

  • C7. Write texts with a structure appropriate to the communication objectives.

  • C11. Operate appropriately to understand and produce a text in written, oral or audiovisual form and interpret and understand the plurilingual, multilingual and intercultural relationship of their immediate reality.

  • C27. Formulate a critical judgment regarding a reality presented using arguments, being able to show collaborative work skills in various groups and to recognize the right of people to participate in issues that affect them, also identifying the challenges of the circular economy and current solutions in the field of industrial technical engineering.

Presentation of the subject

The purpose of the Electrical Engineering subject is to train students so that they are able to understand, interpret and perform calculations in electrical circuits linked to the electrical network (electrical engineering) and electrical machines. Only the permanent regime will be considered, the transitory regime will not be the subject of study. The subject is very strongly supported by the contents developed in the first year subject Electrical Systems. On the other hand, the contents studied here support other disciplines such as Power Electronics, Automation and Robotics.

The classroom (physical or virtual) is a safe space, free of sexist, racist, homophobic, transphobic and discriminatory attitudes, either towards students or towards teachers. We trust that together we can create a safe space where we can make mistakes and learn without having to suffer prejudice from others.

Activities and evaluation system

The final grade (QF) of the subject is calculated as follows:

QF = EX 0,7 + P 0,2 + T 0,1

EX=0,5 Ex1+0,5 Ex2

Ex1 and Ex2: exams

Q: internships

T: work

Minimum grades:

In case the EX activity rating is less than 3,0, QF = EX.

In case the activity rating P is less than 3,0, QF = P.

In case the activity rating T is less than 3,0, QF = T.

If the subject is not passed in the ordinary assessment, there will be an extraordinary recovery session for activities Ex1 and Ex2. The grade of this recovery will replace that of Ex1 and Ex2 activities within the evaluation of the subject. P and T activities are not recoverable.

 

Important:

Any form of academic fraud will be sanctioned in accordance with the regulations
evaluation of the center. In the event that signs of fraud are detected, including the improper use
of generative artificial intelligence tools, the subject's teachers will be able to
call the student for an individual interview with the aim of verifying
the authorship.
