We Know that in conductive Solids there are lots of free electrons available & they drift when electric field is applied. Their drift velocity is in the range of mm/sec to cm/sec. Now if we consider any conductive liquid which is flowing & we connect the electrodes in such fashion that the flow of liquid is in or opposite direction of the electrons. (let's assume the liquid is Mercury). So will the velocity of the liquid medium affect the value of electric current? or more precisely will it affect the resistance? What happens when the flow becomes turbulent?
