A conductor of length l is connected to a d.d. source of potential V. If the length of the conductor is tripled by streaching it, keeping V constant, explain how do the following factors vary in the conductor. 1) drift velocity 2) resistance

A conductor of length l is connected to a d.c. source of potential V. If the length of the conductor is tripled by streaching it, keeping V constant, explain how do the following factors vary in the conductor. 1) drift velocity 2) resistance

If the radius of the earth were increased by a factor of 2 keeping the mass constant, by what factors would its density have to be changed to keep g same?

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?

If p.d. V applied across a conductor is increased to 2V, how will the drift velocity of the electron change?
