I first thought about the resistance to current flow in a vacuum because of curiosity about the orbiting of electrons around the nucleus of an atom. The orbitting electrons seem to be an electric current going through the empty space between atoms. Now on a larger scale any matter travelling through space will continue on forever unless it encounters an outside force. Since light also travels through space with no resistance, a current should flow through a vacuum with zero resistance, regardless of whether electrons are particles or waves.
