A conductor of length L is connected to a dc source of emf `epsilon`. If this conductor is replaced by another conductor of same material and same area of cross-section but of length 3L, how will the drift velocity change?

Define the terms (i) drift velocity, (ii) relaxation time. A conductor of length L is connected to a d.c. source of emf epsi. If this conductor is replaced by another conductor of same material and same area of cross-section but of length 3L, how will the drift velocity change ?

(a) Using Ampere.s circuital law or Biot Savart.s law, show that magnetic flux density .B. at a point P at a perpendicular distance.d from a long current carrying conductor is given by: B=(mu_0/(4pi)) (2I)/a (Statement of the law is not required) (b) Define the terms (i) drift velocity, (ii) relaxation time. A conductor of length L is connected to a d.c. source of emf E. If this conductor is replaced by another conductor of same material and same area of cross-section but of length 3L, how will the drift velocity change?

A conductor of length L is connected across a dc source of e.m.f E. If the conductor is replaced by another of the same materials and area of cross-section but of length 5 L, by what factor will the drift velocity change?

How the resistance of conductor depends on its length and area of cross-section ?

Find the relation between drift velocity and relaxation time of charge carriers in a conductor . A conductor of length L is connected to a d.c source of emf 'E' . If the length of the conductor is tripled by stetching it, keeping 'E' constant , explain how its drift velocity would be affected.

A conductor of length I is connected to d.c. source of potential v. if the length of the conductor is doubled by stretching it, keeping V constant, explain how do to following factors vary in the conductor Drift velocity.
