Current and Drift Velocity (4:54)
|
We explore the concept of electric current and conventional current, which is the direction that positive charges flow, and the reality that electrons move in the opposite direction in most circuits. We derive the equation for average current in terms of the number of charge carriers passing by a point in a wire, charge carrier density, and drift velocity.
