If a current of 0.5A flows through a metallic wire for 2 hours, then how many electrons would flow through the wire ?

(a) Why do the 'free electrons' , in a metal wire , flowing by themselves' not cause any current flow in the wire ? Define drift velocity' and obtain an expression for the current flowing in a wire, in terms of the 'drift velocity of the free electrons. (b) Use the above expression to show that the 'resistivity ' of the material of a wire is inversely proportional to the 'relaxation time' for the 'free electrons ' in the metal.

An electric current of 16 A exists in a metal wire of cross section 10^(-6) m^(2) and length 1 m. Assuming one free electron per atom. The drift speed of the free electrons in the wire will be (Density of metal = 5 xx 10^(3) kg//m^(3) atomic weight = 60)

Assertion : Current flows in a conductor only when there is an external electric field within the conductor. Reason: The drift velocity of the electrons is directly proportional to the electric field.

Two cylindrical rods of uniform cross-section area A and 2A , having free electrons per unit volume 2n and n respectively are joined in series. A current I flows through them in steady state. Then the ratio of drift velocity of free electron in left rod to drift velocity of electron in the right rod is ((v_(L))/(v_(R))) is
