"Webbbe asked if Ohm's law would still be valid. To answer that question one could refer to some laws and theories, but these led to two diverging results. Both arguments were based on the idea of the current-flow as a movement of electrons that could be treat ed as a flow of fluid and the equations of hydrodynamics could then be applied.
