the drift velocity vd and applied electric field of a conducter are related as
Answers
Answer:Drift Velocity is the velocity with which an electron travels in an current carrying conductor.In general, an electron in a conductor will propagate randomly at Fermi velocity, resulting in an average velocity of zero.
It is denoted by Vd.
Vd = -eEtou/2m
where, e is the elementary charge,E is the applied electric field , m is the mass of electron and tou is the average relaxation time for free all the free electron in that conductor.
Explanation: Drift velocity is proportional to current. In a resistive material it is also proportional to the magnitude of external electric field. When potential difference is applied across a conductor, free electron gain velocity in the opposite direction to the electric field between successive collision.
