Question

What is drift velocity and mobility? Establish the
relation between (i) drift velocity and current and
(ii) mobility and current.​

Answer 1

Answer:

Relation between current and drift velocity:

Consider a conductor XY of length L and area of cross section A (Fig ). An electric field E is applied between its ends. Let n be the number of free electrons per unit volume. The free electrons move towards the left with a constant drift velocity vd.

Mobility: The drift velocity of electron per unit electric field applied is mobility of electron. Its SI unit is m2s-1V-1. Relation between current and drift velocity: ... The free electrons move towards the left with a constant drift velocity vd.
