Electrotechnical Material Science
Description: The course "Electrical Materials Science" includes lectures and practical classes, SRSP, as well as independent work of the student on the study of this discipline. This course covers the basics of physics of processes occurring in magnetic, conductive, semiconductor and dielectric materials. The behavior of materials under the influence of magnetic, electric, thermal fields, as well as mechanical influences, the action of the environment is described. The classification of various electrical materials, the scope of their application and the requirements applied to them are given.

Goal
- The study of physical phenomena that occur in materials when they are introduced into the electromagnetic field, as well as the study of the properties of materials, applications in electrical installations and production technology.
Objective
- the study of the structures of materials, as well as the definition of applications in the field of electric power (in electrical engineering, in power engineering, in radio engineering), to study the basic properties of materials; to study the physical phenomena occurring in electrical materials under the influence of electromagnetic fields.
Learning outcome: knowledge and understanding
- After studying the discipline, students should be able to: find the relationship between the structure of matter and the properties that determine the further use of materials in electrical engineering. Know the properties of modern electrical materials, their application. Understand the dependence of the reliability of the power system on the correct choice of electrical materials.

Learning outcome: formation of judgments
- After studying the discipline "Electrical Materials Science", a student can independently answer the questions that arise when choosing the type of materials, and solve the problems that arise during the operation of this material
Learning outcome: communicative abilities
- Intelligence, organization, ability to work in a team, observation
Learning outcome: learning skills or learning abilities
- the student can independently solve the tasks set according to the plan, perform individual tasks, prepare articles and publications
Teaching methods
. In the conditions of credit technology of training, classes should be conducted mainly in active and creative forms. Among the effective pedagogical techniques and technologies that contribute to the involvement of students in the search and management of knowledge, the acquisition of experience in solving problems independently, it should be highlighted: -technology of problem- and project-oriented learning; -technologies of educational and research activities; - communication technologies (discussion, press conference, brainstorming, educational debates and other active forms and methods); - case study method (situation analysis); -game technologies, in which students participate in business, role-playing, simulation games; - information and communication (including distance education) technologies.
Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
| B- | 2.67 | 75-79 | |
| C+ | 2.33 | 70-74 | |
| C | 2.0 | 65-69 | Satisfactory |
| C- | 1.67 | 60-64 | |
| D+ | 1.33 | 55-59 | |
| D | 1.0 | 50-54 | |
| FX | 0.5 | 25-49 | Unsatisfactory |
| F | 0 | 0-24 |
