In theory, yes, but in practise there will be things that cause that
calculation to be inaccurate.  The main issue is that simply measuring a
resistance when the generator is not running is not a good way to determine
the true impedence.  It would be better to measure the open circuit voltage
and the voltage under a known load.  That will give you a much better idea
of the true impedence in practise, from which you can get better estimates
of voltage and current under different load and speed conditions.
