Basics of Electrical Engineering, Electrotechnics, Electronics and Electric Machines
This book is especially dedicated as the fundamental background knowledge, to the
students of Hybrid and Electrical Vehicles, Engineering, provided by Warsaw University of
Technology. Anyway, it seems, it could be also useful for other students of Mechanical and
Electrical Engineering Faculties, participating in English lectures.
