    Drift velocity of electrons is due to

    A) motion of conduction electrons due to random collisions.

    B) motion of conduction electrons due to electric field \[\vec{E}.\]

    C) repulsion to the conduction electrons due to inner electrons of ions.

    D) collision of conduction electrons with each other.

    Correct Answer: B

    Solution :

    [b] Motion of conduction electrons due to random collisions has no preferred direction and average to zero. Drift velocity is caused due to motion of conduction electrons due to applied electric field E.
