How to learn mechanical design and manufacturing without electricity? I was promoted to a higher vocational school from a technical secondary school. I applied for mechanical design and manufacturing, but I can't learn electrician at school! Personally, I think I should give priority to self-study. If I don't understand, I'll teach those who understand. If you go to the book mall, there are still many books about electrician. Just study electrotechnics for mechanical majors, which are divided into analog electronics and digital electronics. You don't need to learn as deeply as electronics and automation majors, just master basic electronic components and circuits.

Electrotechnics, edited by Qin Zenghuang of Harbin Institute of Technology, is divided into two volumes. It is blue-skinned. I don't know if the cover is changed now. It is easy to understand and practical. It is specially compiled for mechanical majors. Personally, I think it is good. You can see if it is suitable.
