RE: [CAD_CAM_EDM_DRO] stepper amperage question

~If the resistance of the load remains the same then doubling the voltage

~R=1 ohm then I will be 1 amp. However, if E is doubled then E=2 volts so I
~will become 2 amps.

Unless the resistance is doubled. then the amperage is one...E also = I X
R. Therefore, if the volts are 2 then 2 X 1 is still 2. It's still a
ratio. I don't want to be didactic, but from my limited understanding of
electricity, resistance plays every bit a part as the others.
