The theme of this course is the analysis of electric circuits. Especially D.C-circuits and A.C-circuits. The theory of magnetism and its application will be also discussed. The various components and interconnection of an electrical system comprise what is described as an electric circuit, and a circuit diagram is a graphic representation of an electric circuit. It provides the basic concept of electric circuits.The laboratory main topics of this course includes: Use of meters (AV)；DC. AC. Voltage；Resistor and Ohm’s Law；Serial and Parallel circuit and Kirchhoff’s law；Super position theory；DC power testing and maximum power output testing；RLC in Series (resonance)；RLC in parallel；.LC pass-filter testing；Characteristics of Transformer Testing；Thermal Resistor and Thermo-control circuit testing； Oscilloscope Training; AC-DC Testing； Speed and power of a motor；Generator；Fundamental Design of Transmission and Distribution system。
