Consider the Segment of Cylindrical Metal Wire Shown Below BB Is Tilted So That Its Nose Vector Makes an Angle

Question 80

Multiple Choice

Consider the segment of cylindrical metal wire shown below. Assume that the drift speed of electrons is everywhere the same in the segment.
 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  \theta<90^{\circ}  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.
