Reading method
Reading a book once can't solve the problem. Reading a book alone is not enough. When reading a book, read it through once or twice before reciting it when you can understand it. If you don't understand, just put it aside for a while and continue reading. Don't read it intensively the first time, just want to understand all the problems in the book. In learning, you should take one as the main teaching material, supplemented by many books of the same type as reference books. When there are incomprehensible parts in the main textbook, refer to the relevant parts of other books.
Theory and practice
Theory cannot be divorced from practice, and practice should be guided by theory. It is a good way to read books, do them manually and stagger them. Problems encountered in practice, consult books. This method of reading with questions is much better than simply reading.
Hands-on operation
We should start with something simple, such as getting familiar with the appearance characteristics of some common components and learning to test their quality with a multimeter, instead of repairing electrical appliances at the beginning.
Fundamentals of electrical and electronic technology
The fundamentals of electrical and electronic technology include the basic knowledge of electrical and electronic technology, low-voltage electrical appliances and electrical measurement, AC circuits, motors and transformers, common electronic devices and their applications, integrated operational amplifier combinational logic circuits, sequential logic circuits, etc.
