September 07, 2010 University Physics, Chapter 25 23 Drift Velocity (1) ! In a conductor that is not carrying current , the conduction electrons move randomly (thermal motion) ! When current flows through the conductor, the electrons have an additional coherent motion (drift velocity, v d ) ! The magnitude of the velocity of random thermal motion is on the

Unformatted text preview: order of 10 6 m/s while the magnitude of the drift velocity is on the order of 10-4 m/s ! We can relate the current density J to the drift ! velocity v d of the moving electrons j = e ( n + v + − n − v − ) Here v is averaged drift (!) velocity Thursday, September 23, 2010...
