Question

relation between current density and drift speed
​

Answer 1

Drift velocity ′vd′ is given by, vd=lt , where 'l' is the length of the conductor and 't' is the time taken to cover that distance. The total charge in the conductor will be, Q=n. ... e , where 'n' is the electron density of the conductor. Hence, Current will be, I=n.A.l.et=n.
