This book is written to help beginners quickly master the basics of circuits from scratch. Unlike traditional textbooks on the basics of circuits, this book abandons the use of advanced mathematics and a large number of formula calculations and quantitative analysis. It focuses on qualitative and conceptual, basic knowledge and practice, and uses simulation experiments with computer simulation software to make the learning of basic knowledge not boring or profound. The basic knowledge of circuits introduced in this book includes: basic laws, theorems and basic analysis methods of circuits, magnetic fields and magnetic circuits, AC circuits, mutual inductance and transformers, and the transition process of circuits. This book comes with a CD containing a trial version of the latest circuit simulation software Edison, which can be used by readers when learning the basics of circuits. This book can be read by technicians, mechanics, electrical workers, home appliance maintenance personnel, and radio enthusiasts in industrial and mining enterprises. It can also be used as a textbook or teaching reference book for secondary technical schools and secondary technical schools.

- Introduction:Answers to the fifth edition of Circuit Model and Circuit Law Circuit theory mainly studies the electromagnetic phenomena that occur in circuits, and uses physical quantities such as current, voltage and power to describe the processes involved. Because circuits are composed of circuit elements, the performance of the entire circuit depends not only on the connection method of the elements, but also on the characteristics of each element. This determines that the current and voltage of each branch in the circuit are subject to two basic laws, namely: (1) Constraints on the properties of circuit elements. Also known as the volt-ampere relationship (VCR) of circuit elements, it is only related to the properties of the elements and has nothing to do with the connection method of the elements in the circuit. (2) Constraints on the circuit connection method (also known as topological constraints). This constraint relationship has nothing to do with the properties of the elements that make up the circuit. Kirchhoff\'s current law (KCL) and Kirchhoff\'s voltage law (KVL) are the basic laws that summarize this constraint relationship. Mastering the basic laws of circuits is the basis for analyzing circuits. Equivalent transformation of resistor circuits \"Equivalent transformation\" is a very important concept in circuit theory, and the method of circuit equivalent transformation is a method often used in circuit problem analysis. The so-called two circuits are equivalent to each other, which means that (1) the two circuits with different structural parameters have the same voltage and current relationship at the terminals and can therefore be replaced with each other; and (2) the effect of the replacement is not to change the voltage, current and power in the external circuit (or the part of the circuit that is not replaced). It can be concluded that the condition for circuit equivalent transformation is that the two parts of the circuit that are replaced have the same volt-ampere characteristics. The equivalent objects are the voltage, current and power in the external circuit (or the unchanged part of the circuit). The purpose of equivalent transformation is to simplify the circuit and to easily obtain the required results. It is important to have a deep understanding of the idea of \"equivalent transformation\" and to master the method of \"equivalent transformation\" in circuit analysis.

- Introduction:新编电路分析基础题解 李瀚荪 397页 26.3M 高清书签版
电路分析基础是通信、自动化、电力、计算机等专业的一门重要的专业基础课，一直为学生所重视。编者在多年的电路课程的教学实践中，深深感受到一些学生对电路的基本概念和基本方法的深入理解和灵活应用上存在一些问题，直观反映在解题困难上。为此，我们选择了获全国教材优秀奖、培养了几代人的李瀚荪教授编著的、高等教育出版社出版的《电路分析基础》中的部分习题进行解答，并融入了清华大学、西安交通大学、重庆大学、天津大学和华中科技大学等高校近年来的部分考研试题编写此书，以期对渴望学好电路课程的学生有所帮助。
本书的每章内容由内容提要与学习指导、习题选题和试题分析三个部分组成。学习指导从教师讲授的思路和学生领会思路两个角度阐述了基本概念和基本方法，篇幅不长，力求简明。习题选解以思路为主线，讲清解题切入点，以图化解学生不知从何下手解题的困惑。试题分析中所选的试题一般为综合应用型试题，旨在锻炼学生综合应用知识的能力，起到启迪思维、开阔视野的作用。
