This course imparts the fundamentals of AC circuits. Main subjects include calculations of AC variables and basic electrical properties of AC circuits such as resistancecapacitanceand inductance. Special consideration is paid here to filter (high-pass and low-pass) circuits as well as resonant circuits. The course is completed by a treatment of the fundamentals of transformers.
