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.

Define drift velocity and relaxation time, with reference to the free electron theory of conductors.

(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 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?

Consider a conductor of length 40 cm where a potential difference of 10V is maintained between the ends of the conductor. Find the mobility of the electrons provided the drift velocity of the electrons is 5xx10^(-6) ms^(-1)

A straight conductor of uniform cross section carries a time varying current, which varies at the rate dI//dt = I. If s is the specific charge that is carried by each charge carries of the conductor and l is the length of the condcutor, then the totalt force experienced by all the charge carries per unit length of the conductor due to their drift velocities only is

How does the mobility of electrons in a conductor change, if the p.d. applied across the conductor is doubled, keeping its length and temperature constant?

Figure shows a conical conducting wire connected to a source of emf. Let E, v_(d) , I represent the electric field, drift velocity and current at a cross-section of the wire. As one moves from end A to B of the wire
