Ohm's law counts, as does Kirchoff's (spelling?). In parallel conductors, the total load current will split between the conductors (inverse) proportional to the impedance of the conductors. If the conductors are same size & type, same length, good connections, etc, the current will split evenly. That's the goal, to have evenly loaded parallel conductors.
If the parallel cables are exactly equal, then current, kva, kvar, etc, should be the same in each.
Hope this helps some,
