Hello ,
Is it convenient to ask about or emf and current equation:

Case1:
Chapter 10.4
10.4 Generators
https://web.mit.edu/8.02t/www/802TEAL3D/visualizations/coursenotes/modules/guide10.pdf

Equation : (10.4.3) Emf
Equation : (10.4.4) Current


Case2:
https://digitalcommons.uri.edu/cgi/viewcontent.cgi?article=1027&context=phy204-lecturenotes
Page 5

Case 3:
https://www.physicsbootcamp.org/Motional-EMF-from-Rotation.html
Equation (38.19)
Equation (38.20)

In all the cases above the induced current is EMF/(CoilsActiveResistance + LoadActiveResistance)

Should we consider also Inductive reactance of the generator rotor coil?

Thank you

By the definition that I am aware of, "CoilsActiveResistance " includes all reactance terms as well as skin effect and itergranular obstruction losses.

OK, in introductory textbooks those details are often left out, often because students are not yet aware of those things yet. It is not likely that first year engineering students will actually be designing generators for production. Basic theory comes before all of those nasty details.
AND I am not interested in picking apart introductory first year class materials.
