Electrotechnics

Course Description

DESCRIPTION

The goal of the course is to provide student a wide knowledge of electric circuits. That is, upon successful completion, students will identify and apply different methods for the resolution of electric circuits, and will be able to apply the related terminology and formulation. Electrotechnics is the basis on top of which students will learn to design, analyze and implement any low tension electrical installation, to distinguish and choose the most suitable electrical machine for any given particular need, and to predict their behavior after installation, as well as to determine the most suitable device to solve a problem of control and adaptation of electric energy and to incorporate it in power electronic systems.

OBJECTIVES
- Identify and solve direct current circuits in a transient state based on resistances,
capacitors and inductors.
- Identify and apply various methods in order to solve single-phase alternating current
circuits, using the corresponding terminology, formulae and analytic methods.
- Identify and apply various methods in order to solve three-phase alternating current
circuits, using the corresponding terminology, formulae and analytic methods.
- Identify the main electric machines that can be found in an electric installation, in terms
of its working principles.

METHODOLOGY
In each chapter, the students will identify the various systems they know and find in ordinary
life, involving electric and electronic circuits, showing the importance of its analysis.
The first class hours will be devoted to introduce both the terminology and the main elements
and concepts they will use when studying electric and electronic circuits. The student will use,
besides the proposed basic and consulting bibliography, the Moodle course in order to fulfill the
activities. They must read the proposed documents and will write down all the doubts coming
from this reading. All these doubts will be answered in the class.
The lecturer will explain the chapters in class, solving those doubts that the student may have
after their work at home. At the same time, the lecturer will insert practical exercises within the
contents explanation. The student will solve these practical exercises with the lecturer's aid.
The student will fulfill the following activities:
- Theoretical contents study, along with bibliographical search.
- Long working out problems of analysis and design, both in and out the class.
- Short answer or True/False tests, where the student will give reasons for the choice.
- Exercises with numerical results to be solved by each student from previously explained
methods, in order to obtain design and/or analysis values.
- Experiments in the Laboratory.

ASSESSMENT
The evaluation system consists in the following activities:
-Two intermediate exams: 30%
-Report of the laboratory experiments: 5%
-Final exam: 40%
- Projects: 15%
