What is the relation between drift velocity and electric current?

Establish the relation between drift velocity of electrons and electric field applied to the conductor.

What is a drift velocity ? Establish the relations between the drift velocity and electric current.

Write the mathematical relation for the resistivity of a material in terms of relaxation time, number density, mass and charge carries in it. Explain using this relation, why the resistivity of a metal increases and that of semiconductor decreases with rise in temperature.

The figure SAQ 14(a) shows two identical rectangular loops (1) and (2) placed along with a straight long current carrying conductor between them. What will be the direction of induced currents in the loops when they are pulled away from the condutor with the same velocity v?
