When electric field `(vec(E))` is applied on the ends of a conductor, the free electrons starts moving in direction

When electric field (vecE) is applied on the ends of a conductor, the free electrons starts moving in direction

When electric field is applied inside a conductor then free electron are accelerated. Their average velocity in time interval t is proportional to

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. The magnitude of electric field set up across the ends of the conductor is given by

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. Magnitude of acceleration produced in each electron by the electric field is

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. Mobility of free electron is

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. Average thermal velocity of the electron is
