书籍介绍
这本书最打动人的地方，是它把那些散落在工程师记忆里、却从未被系统讲清的基本概念重新打捞起来。读者反复提到的，是R、L、C背后的物理直觉——电感存于磁场、电容藏于电场，电压建电场、电流生磁场；是'电阻=电压/电流''质量=(力×时间)/速度'这类跨学科的类比，让人忽然看懂为什么'基础'二字值得记在脑子里。它不追求严谨完整，反而被不少读者指出'笼统''有些地方不准确'，但正是这种'当小说看'的轻松，让复杂器件背后的直觉变得可感。它适合刚入行、或多年后想重新校准工程直觉的人：翻完未必记得全部公式，却会留下判断电路'大概会怎样'的能力。

精彩摘录
- "Cool application note: using two transistors to switch a signal level Vcc PNP switched by NPN."
- "电压*电流=功率 阻尼系数=阻尼力/速度"
- "电阻=电压/电流 质量=(力*时间)/速度 电感=(电压*时间)/电流"
- "“Lego” Engineering You can always look up the more advanced stuff, but most of the time a solid application of the basics will force the problem at hand to submit to your engineering prowess. These six rules are things that you should memorize, understand, and be able to do approximations of in your"
- "Thumb Rules ■ Electricity is fundamentally charges, both positive and negative. ■ Energy is work. ■ There are just as many positive as negative charges in both a conductor and an insulator. ■ In a good conductor, the electrons move easily, like liquid water. ■ In a good insulator, the electrons are "
- "Voltage generates an electrostatic field (it is this field repelling or attracting other charges that creates the voltage “pressure” in the conductor). Current or flow or movement of the charges generates a magnetic field around the conductor."
- "The charges in the wire are moving much more slowly than one might think. In fact, DC current moves at about 8CM per hour. (In a typical wire that is, the exact speed depends on several factors, but it is much slower than you might think.)"
- "Thumb Rules ■ An accumulation of charges is what we call voltage. ■ Movement of charges is what we call current or amperage. ■ Energy is work; in a circuit the electromagnetic effects move energy from one point to another."

20201017周六，办公室，看了一大半，和第一版相比，就有部分改动，昨天看第一版的后半部分，今天看了这一版的前半部分，当然还不够，还需要反复看。
让我对什么是垃圾的书有了一个形象的认识
这本书应该算是速食消费学科知识的快餐文化，但又不仅仅是知识的提纯，而是用一种基于个人经验的讲解；对于部分内容，虽然站在更深学科内容的角度上觉得如此讲解的确不合适，但是的确是这个理。
非常好的入门书
比较基础，有趣的入门书籍。
很好的工具书
好书！
