Version 1. 0 [Electronic resource] Workshop. - Krasnoyarsk: IPC SFU, 2008. 335 s. This edition is part of the electronic educational and methodological complex in the discipline "Theoretical foundations of electrical engineering" , The training program, Training Manual , Workshop, Guidelines for independent work , Guidelines for laboratory work , Control and measurement materials "Theoretical foundations of electrical engineering . Bank of test tasks", as well as a visual aid "Theoretical foundations of electrical engineering . Presentation materials" . Methods of calculation of linear electrical circuits at constant, sinusoidal and non-sinusoidal effects. The analysis of processes in single-phase and three-phase chains. Nonlinear electric and magnetic circuits of direct and alternating currents, transition processes, as well as circuits with distributed parameters. are considered. Presented tasks and explanations for their solution, as well as tasks for self-control with answers. Intended for undergraduate students 140200. 62 "Power Engineering" and 140600. 62 "Electrical engineering, electromechanics and electrotechnology" of the enlarged group 140,000 "Energy, power engineering and electrical engineering" .
