Current and Drift Velocity

The video tutorial explains electric current, its symbol, and units. It differentiates between instantaneous and average current, and discusses the concept of conventional current versus actual electron flow. The tutorial models current flow using positive charges and introduces equations for average current. It covers charge carrier density, drift velocity, and derives the current equation. The tutorial concludes with a summary of the concepts discussed.
