You are not applying ohms law to the transformer correctly
when stated the way you have. If you apply 100 volts to a
10:1 transformer you will end up with 10 volts out. If you
put a 10 ohm resistor on the secondary you will have one
ampere passing through the resistor. In an ideal
transformer the 100 volt source will be sourcing .1 amps.
Increase the primary voltage by a factor of 2 and the
secondary voltage will increase by the same. The amps in
both windings will increase by a factor of 2 as well. Ohms
law has not been violated.
