Unformatted text preview: the same magnitude of I as for a forward voltage of the same magnitude. The I versus V graph for an ohmic resistor is sketched in Figure 29.24. Figure 29.24 29.25. Set Up: The resistance is defined to be Solve: (a) The graph of V as a function of I is sketched in Figure 29.25. Figure 29.25 (b) If R is constant the graph of V versus I is a straight line. This is not strictly the case in either region. Reflect: For large forward currents the resistance is approximately constant and very small. For large reverse bias currents the resistance is approximately constant and very large. V I R 5 V I . I V R 5 V / I . Atoms, Molecules, and Solids 29-5...
