Subject aims expressed by acquired skills and competences
The purpose of this course is that students get an idea of the basic principles of electrotechnics, to a degree necessary for Mining Engineering Faculty graduates. Students should be able to understand the connection between these theoretical principles and practical ways of using electrical energy. Special attention should be paid to practical things that students will need in their future career.
Students will also learn basic facts about protection against injuries in electrotechnics, and the most important legal regulations that they can encounter.

Summary
The subject resumes on knowledge of Basic of Electrical Engineering got at
physics. Students are acquainted with solving of electrical circuits,
principles of the measurement of electric and non-electric quantities, with
function principles and operation properties of electrical machines and
instruments; with elements of electrical drives, solid-state engineering,
electrical heat and with elements of production and distribution of electrical
power. Specifications of concept methods of electric current injury protection
are a part of the education too.
