Define drift velocity and write its relationship with the current flowing through it.

Define the term 'drift velocity' of charge carriers in a conductor and wire its relationship with the current flowing through it.

Define 'drift velocity' of free electrons .

Give relationship of drift velocity with the current flowing through in conductor.

When a current of 1 A flows through a copper wire of cross sectional area 1mm^2 the drift velocity of free electrons becomes v, What will be the drift velocity of free electrons when the same current flows through a copper wire of cross sectional area 2mm^2 ?

Define 'Drift Velocity' and 'Relaxation time'.
