"Voltage = Current(I) x Resistance"
This formula is for DC Circuits, AC is different.
"A 6 volt system has to push more current at than a 12 volt system at the same resistance."
Not true. Look at the formula. It is however true for wattage, not resistance. Wattage is a rating for power.
Wattage= voltage x current
Identical items of different voltage ratings often have the same or close to the same wattage ratings. A 12volt light bulb would use half the current of a 6volt bulb of equivalent wattage.
