Arectangular parallelipiped "wire" of length 1.4m , height 6.4ã10â2m , and depth 2.5ã10â2m lays with its end faces parallel to the xy -plane. the depth runs parallel to the x -axis and the height runs parallel to the y -axis. the centers of the end faces coincide with the z -axis. a constant potential difference of 380vis maintained between the two end faces. as it turns out, the density of current running along the length of the wire depends on position like j(rx, ry)=41a/m6r2xr2y .
