Course record
Electrical Machines
I revisit magnetic circuits, transformers, and rotating machines around my transformer report and calculation sheets.
Unit numbers expand the saved report and calculations into a reading sequence rather than an attendance record.

How I use this hub
I open one unit at a time, restate the core terms, and compare equations, circuits, code, and saved results.
