SYLLABUS ZA PREDMET
This course enables the students to understand the notions, basic laws and principles related to
the direct electrical circles and electro-statics. The students will be able to analyze the direct electrical circles
and the phenomena related to electro-statics, and to understand the physical phenomena taking place in them.
Methods and ways of encouraging the achievement of the learning
outcomes and the general and specific competences
To realize the learning outcomes and related competences, the technology of the classes is
based upon the lectures, observatory-experimental methods, auditory exercises, practical and
laboratory exercises, seminary works, homeworks and the field classes. The lectures and the
auditory exercises are implemented every week in two terms, according to the time schedule 2
+ 2 hours. Laboratory exercises are implemented in 2 cycles for now, according to the plan of
course realization.
3. COURSE IMPLEMENTATION
Lectures
The lectures are conducted according to the executive teaching program. The content of the
course is divided into the thematic units which are processed in weeks of classes. The topics
are grouped in three cycles. After each cycle, a written examination is conducted (interexamination – partial examination). For each topic, the students can read a PDF document
with detailed description of the contents which will be the topic of the lectures.
Auditory exercises
The content of the course is practiced through the sloving of the numerical tasks, in sudh way
that the theoretical knowledge is completed through the practical numerical exemplaries, and
the knowledge of the general laws is strengthened.
Laboratory exercises
After each cycle of lectures, the classes in laboratory are conducted, where the students are
introduced to the practical electrotechnics. In our web sites, the students can find the most
important data for preparation of these exercises (laboratory papers with the required
introduction, preparatory tasks and the manner of implementation of exercises etc.)
Electrotechnics 1: Instructions for the laboratory exercises 1. Before attending the
exercises, the students have to be prepared (by making the preparatory tasks), which will
be evaluated by the exercise facilitator. One group consists of maximally 2 students. Each
cycle of exercises can be the subject of evaluation on the final examination or on the
following partial examination.
DINP: ELEKTROTEHNIKA 1

SYLLABUS ZA PREDMET
Homeworks
During the semester, the students are given harder tasks from the field of mixed joints of
resistors, linear networks and electrostatics, which have to be solved according to the given
instructions and submitted according to the deadline defined by the plan of execution of
specific activities. As a rule, 2 homeworks have to be done.
Seminary
During the semester, the students are given one seminary paper from the field of alternating
networks, bridges of alternating current, magnetic circles, calculation of transformers and
silencers etc., which have to be solved according to the given instructions and submitted
according to the deadline defined by the plan of execution of specific activities. Seminaty
paper is a teamwork of theoretic and practical contents, and the results of the work are
presented in public.
Tests/exercise tasks
Beside the testings made with the goal of grading and ranking, the students have at their
disposal tests (tasks) for self-examination of knowledge for every unit of the course; these are
a part of preparation for the inter-examinations (partial examinations). The tests are solved
independently, or in cooperation with the teachers. Although every question can be part of
examination, it is still useful and necessary to answer the questions from the previous
examinations. When the students prepare for examination, it is recommended to solve such
question individually.
Simulations and virtual laboratory
For better physical and mathematical explanation of individual parts of the course content,
there are adequate programs (these are the programs intended for the „transport“ within the
Internet), which can help in understanding of the individual physical-phenomenological
events related to electrotechnics. Individual „visualization“ contains the adequate description
of the physical phenomena, as well as the instruction for program operation.
Contemporary teaching methods include the computer technology in various manners. Beside
the large number of educative programs at the local level, in recent times, global systems of
teaching have been developed, which are based upon the implementation of Internet. By
distribution of the interactive teaching contents through the Internet network, their availability
and actuality is increased. Traditional forms of the classes are supplemented or even replaced
by the so called distance learning, where the notion „distance“ is to be understood in the sense
that the student is not at the same place as the teacher. Here we have shown the part of the
course content Electrotechnics 1 which relate to the simulations and animations of the
experiment, i.e. to the visualization and explanation of some physical phenomena.
Computer technology enables the so-called virtual experiment. Of course, the virtual
experiment, i.e. simulation cannot replace the real experiment completely, but it can help in
preparation of execution of the real experiment, or it can be the supplement of the real
experiments. Certain real experiments, especially those from the fields of electro-statics and
magnetism, which require expensive equipment and specific environment, can be replaced by
DINP: ELEKTROTEHNIKA 1

2009
SYLLABUS ZA PREDMET
the virtual experiments, with additional explanations. With the use of Internet, the
experiment can be transferred and reproduced in every location.
Consultations
For all questions and issues related to the course content, the students can ask other students,
assistants and professors. With this purpose, they are given the e-mails of the teaching
personnel and the possibility of personal consultation with the teachers in the defined terms.
Poll questions
On the initial page, there are poll questions with the goal of improvement of the classes. Poll
questions are changed during the semester (teaching process). Since the poll questions are a
part of the teaching process, the students are obliged to answer them (polls are anonymous).
Student obligations
During the individual cycle of the classes, the obligations of the students are:
- regular attendance and participation in classes;
- making of all laboratory exercises;
- writing and timely submitting of homeworks;
- teamwork in writing and making of the seminary paper;
- preparation for the examination (inter-examination), as well as for other tests of knowledge.
For preparation of the inter-examinations and final examinations and other tests of
knowledge, the students have, beside their notes from the lectures, the following course
materials on their disposal:
- slides from the lectures on Web;
- numerical tasks for exercises (Collection of exercises from Electrotechnics 1) as the
written material in the form of scripts, which can be acquired in the School administration
department.
- consultations with the teacher in accordance with the published weekly schedule.
Various course materials can be found on the WEB sites of Electrotechnics.
Evaluation of the achieved outcomes in learning (grading of the acquired
knowledge)
Each cycle is completed with the written examination (inter-examination or partial
examination). The examination is taking place in the week after the class cycle,
simultaneously for all students. After the last cycle of lectures, the students write the third
inter-examination and the final examination. The final examination consists of the written
part, which is also the third inter-examination, and envelops the last cycle of lectures, and the
oral part, which envelops the questions from the whole course content.

4. FORMS OF KNOWLEDGE EVALUATION AND GRADING
During the semester, the attendance of the students on the classes is monitored, and the
execution of the obligations is evaluated.
After each course unit, the evaluation of the students' knowledge is conducted through the
oral examinations and through the quick tests; these tests are not graded.
After each cycle of lectures, students have to pass the inter-examination. A student who does
not achieve the required minimal result is obliged to repeat the inter-examination. At the end
of the course, the students approach the final examination.
The criteria for approaching the final examination for the students are following.
- Regular attendance on the classes (of 30 classes, they can be absent 8 times);
- Activity on classes;
- Passing of all laboratory exercises;
- Writing the homework on time;
- Writing, making and presenting the team seminary work;
- Passing of all three inter-examinations.
The students who have not achieved enough number of points on the final examination to get
the positive grade will be enabled to approach another evaluation of knowledge on repeated
final examination.
Repeated final examination can be approached also by the students who
have achieved positive grade on the first final examination, but are not
satisfied with the grade. Each student who approaches the repeated final
examination will have his/her points achieved on the first final examination
erased.
The students who have not achieved positive grade on the repeated final examination will be
enabled to approach another repeated examination in April.
All the previously mentioned activities and obligations in the course are
evidenced in the students' diary.
