Figure 26-17 shows a rectangular solid conductor of edge lengths L, 2L, and 3L. A potential difference V is to be applied uniformly between pairs of opposite faces of L the conductor as in Fig. 26-8b. First 2L 3L V is applied between the left-right Fig.26-17 Question 3. faces, then between the top-bottom faces, and then between the front - back faces. Rank those pairs, greatest first, according to the following (within the conductor): (a) the magnitude of the electric field, (b) the current density, (c) the current, and (d) the drift speed of the electrons.
