课程名称：电气工程导论 课程概述：该课程旨在帮助初学者以最简单、高效和快速的方式学习电气工程的基本原理。课程不一开始就提供所有信息，而是根据学员的提问和需求逐步引入内容，这种方法已被证明是学习语言和其他知识的最佳方式。请积极提问，进行主动学习！课程内容首先介绍电气工程的各个分支（如信号处理、控制系统、电力系统、通信、光子学、微电子学）及电气工程师的工作内容。接下来，你将学习电气工程中常用的基本组件的特性（如电阻、电容、电感、电源、电压表和电流表）。在理解欧姆定律和直流电路分析（如基尔霍夫电压定律和电流定律）之前，课程会通过实例展示电压、电流、电荷和功率的含义。 课程的第二部分涵盖主动电路元件（如运算放大器、二极管和晶体管）。你将学习它们的特性及典型应用。之后，我们将重新审视被动元件，了解它们在交流电路中的表现。在这一部分，你将学习复数在交流电路的存在原因、如何进行复数运算以及相位差的概念。最后一部分集中于电力的生成、损耗和分配，同时介绍熔断器和变压器。课程的最后，我们将探讨实际电路，遵循一些指导原则，帮助你开始构建自己的电路。
The goal of this course is for you (an absolute beginner) to learn all the fundamentals of Electrical Engineering in the most simple, effective and fast way. Instead of giving you every information at the beginning and bore you with all the details, I will add information as you start to question and start to need it. This is proven to be the best way to learn languages and I believe it's the best way to learn anything. So please ask questions and learned actively! This course starts with explaining what all the sub-fields in Electrical Engineering (e.g. Signal Processing, Control System, Power System, Telecommunication, Photonics, Microelectronics) are and what Electrical Engineers do. Then you will learn the characteristics of the most basic and common components used in Electrical Engineering (i.e. resistors, capacitors, inductors, power supplies, voltmeters and ammeters). Before you can understand Ohm's Law and DC Circuit Analysis (e.g. Kirchoff's Voltage Law and Kirchoff's Current Law), I will demonstrate what electrical voltage, current, charge and power means with examples. The second section of the course covers active circuit elements (i.e. operational amplifiers, diodes and transistors). You will learn their characteristics and typical applications. Then we will revisit the passive components and see how they behave in AC circuits. In this part, you will learn why complex numbers exist in AC circuits, how to perform complex number algorithms, and what phase shift is. The last part of this section focuses on power generation, losses and distribution. Here we will introduce fuses and transformers. Lastly, we will look at practical circuits and follow a few guidelines to help you start building your own circuits.
