What is drift velocity? Derive expression for drift velocity of electrons in a good conductor in terms of relaxation time of electrons?
Solution
When a potential difference is applied across a conductor, then an electric field is established due to which every free electron acquires a definite velocity in a particular direction, this is known as drift velocity.
