Учебное пособие, написанное на английском языке, составлено в соответствии с программой курса "Теоретические основы электротехники" и предназначено для студентов электромеханических и электротехнических специальностей.
В пособии рассматриваются аспекты синтеза электрических цепей с сосредоточенными параметрами, теории электрических цепей с распределенными параметрами и некоторые вопросы теории нелинейных электрических и магнитных цепей. Данное учебное пособие является продолжением книги К.К. Кима "Линейные электрические цепи", изданной в 2006 году.
The course "Theoretical Fundamentals of Electrical Engineering* consists of the theory of electrical and magnetic circuits and the theory of electromagnetic fields. This course (according to the curriculum) is taught during three semesters.
The synthesis of electric circuits with lumped parameters, the aspects of the theory of electrical circuits with distributed parameters and some problems of the theory of nonlinear electrical and magnetic circuits are considered in this tutorial.
The tutorial is done for students of electrical, electronic, control, communication, information, instrumentation and computer engineering specialties.
There are calculation hometasks which are given to the students at the end of the tutorial. There is also a list of the recommended literature for the students.
