Find the current in the wire the resistance of the wire the


An aluminum wire is 10 m long, 0.4 mm in radius, and contains an electric field of 0.5 V/m.

Find

(a) the current in the wire,

(b) the resistance of the wire,

(c) the power dissipated by the wire,

(d) the potential difference between the ends of the wire, and

(e) the current density in the wire. NOTE: density(aluminum) = 2.75x10-8 ohm.meters, D(aluminum) = 2.7 g/cm3, M(aluminum) = 26.98 g/mole.
