A conductor 100 meters long and with a uniform cross section of 107.2 mm2
,
presents a current density of 2.15 x103 A/m2
and a total voltage drop of 3.7 V
between the ends of the conductor.
Find the electric field strength E, the volumetric power density in the
conductor, the current carried and the conductivity of the material.
According to the conductor tables, what gauge does the conductor correspond to? 10%
