Complex Imaginary vol.3 #34

[BebeshKing PE]

Could anyone please tell me what is exactly asked on this problem? I thought  "internal generated voltage" means the Induced stator voltage Eo which is Eo=E+Ex.

But in the solution, it is solving for the Voltage drop Ex.

Thoughts?

I just realized something after I click "Submit Topic".

Maybe because the generator is not loaded? And that is why E=0? 

That being said, are we going assume like this on every problem even the problem did not state that it is unloaded?
