ELECTRICAL ENGINEERING

It is an obvious translation from the author’s native language. The text in most images have not been translated to English. As for style and readability, for a native English speaker, id reads like someone ran it through a poor translation app, or how a non-native English speaker would (poorly) translate as they spoke. Given all that, its hard to evalate the quality of the engineering science or how well it is expained.

Annoying grammatical errors all over. It appears no proof reading was done at all.
