comment good book on differential forms for engineers?
"A course in mathematics for students of physics" by Bamberg and Sternberg is gold, especially for electrical engineers.

I'm voting to close this question as off-topic because it is no longer relevant, as the person asking has already found the answer, as mentioned in the comments.
