Consider the segment of cylindrical metal wire shown below. Assume that the drift speed of electrons is everywhere the same in the segment. Note that area B is tilted so that its nose vector makes an angle of ? < 90° with the drift velocity direction but still spans the wire’s entire cross section. How do the current density fluxes through areas A and B compare?
A. The flux through A is greater than the flux through B.
B. The flux through B is greater than the flux through A.
C. The fluxes through A and B are the same.
