เนื้อหาย่อ : This book is designed for use as a supplement to all current standard texts or as a textbook for a course in circuit analysis. Emphasis is placed on the basic laws, theorems and techniques which are common the various approaches found in other texts. The subject matter is divided into chapters covering duly-recognized areas of theory and study. Each chapter begins with statements of pertinent definitions, principles and theorems together with illustrative and other descriptive material. This is followed by graded sets of solved and supplementary problems. The solved problems serve to illustrate and amplify the theory, present methods of analysis, provide practical examples, and bring into sharp focus those fine points which enable the student to apply the basic principles correctly and confidently. The large number of supplementary problems serve as a complete review of the material of cach chapter. Topics covered include fundamental circuit responses, analysis of waveforms, the complex number system, phasor notation, series and parallel circuits, power and power factor correction, and resonance phenomena. Considerable use of matrices and determinants is made in the treatment of mesh current and node voltage methods of analysis. Matrix methods are also employed in the development of wye-delta transfor- mations and network theorems such as superposition and reciprocity. Mutually coupled circuits are very carefully explained. Polyphase circuits of all types are covered, with emphasis on the one-line equivalent circuit which has important applications. The trigonometric and exponential Fourier series are treated simultancously, and the coefficients of one are frequently converted to coefficients of the other to show their relationship. Direct and alternating current transients are treated using classical differential equations so that this topic can precede the phasor notation of Chapter 5, and this is recommended for those whose proficiency in mathe- matics will permit this arrangement. The Laplace transform method is introduced and applied to many of the same problems treated in Chapter 16 by differential equations. This permits a convenient comparison of the two methods and emphasizes the strong points of the Laplace method. I wish to avail myself of this opportunity to express my gratitude to the staff of the Schaum Publishing Company, especially to Mr. Nicola Miracapillo, for their valuable suggestions and helpful co-operation. Thanks and more are due my wife, Nina, for her unfailing assistance and encouragement in this endeavour.
