Yes, this will work, as long as you make sure that the resistance
values of the resistors are basically equal.

Yes, I've done his myself and it seems to give a pretty decent
"ballpark" figure on the output voltage of the transformer. Example:

120 volts into the HV windings of a 12000 volt transformer should
yield about 1.2 volts on the low voltage side of the transformer
since there is a 100:1 turns ratio.
