Course description

Baseed on the combination of Resistance, R, Inductance, L, Capasistance, C, we consider passive circuits and try to understand the following issues by calculation of characteristics of the circuit. These characteristics are Voltage, Current, Impedance, Frequency and Equiliberium conditions of the circuit. 1. Transformation (including Ideal Transformer) 2. Loop Equation (Loop Current method), Node Equation (Node Voltage method) 3. Basic theorem in circuit analysis such as, Inverse Theorem, Equiliberium Power Sources, Maximum Power Transmission Theorem 4. 2-Ports parameters, Cascading connction, Parallel connection, different operation of 2-Ports circuits

Expected Learning

In this lecture, the students will be able to learn about many Alternative Circuits theory and application. Also, the students will have the ability of calculating and analyzing many AC circuits. In order to have these kinds of ability, the students should solve many problems related to the subject of this course, not only during the lecture but also outside the lecture.

Course schedule

The followings are the contents of the course (these contents might be changed based on the flow of the classes). 1st Class: guidance of the entire course Chapter 7: Transformer 　In this chapter we will study about the basic equation, the characteristics and the features of the transformer. Transformers with single, two or more coils, such as a tight coupling transformer and an ideal transformer, are used for a circuit. We also study about understanding the meaning of mutual-inductance, M, as well. 2nd Class: 2-winding transformer, control source 3rd Class: Auto-transformer, ideal transformer 4th Class: Multi-transformer Chapter 8: Circuit Equation In this chapter we study about the foundations of how to form equations for calculating voltage and current in a circuit. For this sake we use the application of Kirchhoff's law, a loop circuit current method, and a node voltage method. As circuits have R, C, L, and M, then we should understand well that voltage and current are governed by them. 5th Class: Loop Equation 6th Class: Nodal Equation 7th Class: Solution of simultaneous linear equations * Mid-term test will be held after finishing the Chapters 7 and 8. Chapter 9: Theorem and Characteristics for Deeply Understanding of Circuits In this chapter, for deeply understanding the circuits, we study about many theorem such as a Reverse Theorem, Thevenin's Theorem, Norton's Theorem, Compensation Theorem, and the Law of Maximum Power Transmission, etc. 8th Class: Reverse Theorem, Duality, Reverse Circuit 9th Class: Equivalent Power Supply and Compensation Theorem 10th Class: Maximum Power Transmission Theorem Chapter 10: 2-Ports Network Parameters In this chapter we learn about how to express the relation of voltage and current of 2-ports networks by 6 different matrices such as Z, Y, g, h, F, Fi. These 2-Port Networks are widely used in circuit analysis. Also, we study about Input/Output impedance, transmission quantity, repetitive parameter, etc. Moreover, we study about the fundamental characteristic which is needed when using this kind of network. 11th Class: Six different parameters of 2-Ports network. 12th Class: Mutual conversion of parameters in 2-Ports network. 13th Class: Cascade connection and parallel connection of 2-Ports networks. 14th Class: Operations of 2-Ports network 15th Class: Final examination

Assessment/Grading

【Important, Due to Corona Virus Situation】　In case we had the entire classes of this course as ONLINE Lecture】 The grade evaluation in this online class is premised on all attendances, and comprehensively evaluates the attitude to learn, quizzes, report, and online tests. Standard study time set by our university is required to get the grade. The rate of evaluation is as follows: quizzes and assignment test（3 times): 30 points Intermediate online test: 30 points Final online test: 40 points Total points: 100 points Passing Score: 60 points and above Grade will be given according to the following criteria by comprehensive evaluation: S: 90 points or more, A: 80 or more and less than 90 points, B: 70 or more and less than 80 points, C: 60 or more and less than 70 points.

Message from instructor(s)
