The video tutorial explains how current flows in wires through negative electrons and in liquids through charged ions. It discusses the conventional direction of current flow, which is the direction of positive charge movement. The tutorial also covers how current is measured using an ammeter and introduces the ampere as the unit of current, defined as one coulomb of charge passing a point per second.
