  • Lecture Note

    The lecture notes are written for internal use only. The following lecture notes are based on the topics described in the official syllabus of ELECTRICAL CIRCUITS I. The target audience for these lecture notes is students in the B2 in Energy major of the Undergraduate school in USTH. These lecture notes contain five main chapters. They cover most of the major topic areas, but are far from comprehensive in scope. Students are still encouraged to consult one of the recommended text books of [1], [2], and [3] for in depth explanations.

    These lecture notes is devoted to DC circuits. The first two chapters, it covers the passive and active elements, fundamental laws (Ohm, Kirchhoff) and theorems, circuit analysis techniques. An introduction to operational amplifiers is presented in Chapter 3. A few examples and homework problems in later chapters must be skipped. In the last chapter we perform what is normally referred to as a transient analysis. We begin the analysis with first-order circuits--that is, those that contain only a single storage element. When only a single storage element is present in the network, the network can be described by a first-order differential equation. The analysis of first-order circuits begins with the presentation of two techniques for performing a transient analysis: the differential equation approach, in which a differential equation is written and solved for each network, and a step-by-step approach, which takes advantage of the known form of the solution in every case. In the second-order case, both an inductor and a capacitor are present simultaneously, and the network is described by a second-order differential equation. Although the RLC circuits are more complicated than the first-order single storage circuits, we will follow a development similar to that used in the first-order case.

    These lecture notes are a labor of Dr. Nguyen Xuan Truong, assistant professor at Energy department of University of Science and Technology of Hanoi. Many people have contributed and in particular I would like to thank Dr. Tran Thanh Son from Electric Power University, Dr. Nguyen Dinh Quang from Institute Energy Science/VAST. This is a first version and I hope these lecture notes will be improved with the contributions of additional instructors in the 2nd version.
