Why does distilled water produce no flow of electricity when sugar is dissolved in the water?
In order to have a flow of electricity through a solution, ions are needed. In this case, the water is distilled so it doesn’t have ions of its own. We added sugar which dissolves but doesn’t dissociate. So it produces molecules not ions. If we added salt instead of sugar, it would dissolve and dissociate, produce ions and a flow of electricity.
