How to read circuit diagrams (Part 1)

A circuit diagram usually has dozens or even hundreds of components, and their connections are crisscrossed and varied in form. Beginners often don’t know where to start or how to understand it. In fact, electronic circuits themselves have strong regularities. No matter how complex the circuit is, after analysis, it can be found that it is composed of a few unit circuits. It’s like the building blocks that children play with. Although there are only a dozen or twenty or thirty kinds of blocks, they can be built into dozens or even hundreds of plane figures or three-dimensional models in the hands of children. By the same token, no matter how complex the circuit is, after analysis, it can be found that it is also composed of a few unit circuits. Therefore, as long as beginners are familiar with the commonly used basic unit circuits first, and then learn the skills of analyzing and decomposing circuits, it should not be difficult to understand general circuit diagrams. In this special topic, we have not only collected classic books on how to read circuit diagrams, but also collected popular related posts on the Internet. I believe it will be helpful to everyone\'s learning.
