The prefixes FLU, FLUC, FLUX mean

These prefixes come from a root that means to flow, signaling movement in a continuous, streaming way. That sense points to Flow as the best description of what they convey. You can see it in words like fluid, which describes something that can flow; fluctuate, which implies changing in a flowing, up-and-down manner; and flux, a related idea of ongoing flow or change. While current is related to flow and flux is a related noun, the overarching idea the prefixes express is flow, so Flow is the right meaning.
