A current carrying aluminum wire, having diameter of D = 0.10mm and length L = 2 m, consists of a uniform field of E = 0.2V/m imposed all along its whole length. The temperature of the wire is T = 50 C. Suppose that one free electron per atom.
(T = 20 C, r = 2.82x10^-8 ohm*m^2, a = 3.9 x 10^-3/C. Take the atomic mass of the Al as mA= 27 g/mole, density of the Al d = 2.7 g/cm^3 and the Avogadro's number as 6.02 x 10^23 atoms/mole.)
i) Find out resistivity of the wire.
ii) Determine the current density in the wire?
iii) Determine the net current in the wire?
iv) Find out the drift speed of the conduction electrons?
