In Fig. 15.3.3, a typical length and time are considered the independent parameters. Suppose that we wish to see the effect of varying the conductivity with the size held fixed. For example, with not only the size but the frequency fixed, the material might be cooling from a very high temperature where it is molten and an ionic conductor to a low temperature where it is a good insulator. Using the conductivity rather than the length for the vertical axis, select a normalization time for the horizontal axis that is independent of conductivity, and construct a diagram analogous to Fig. 15.3.3. Identify a “characteristic” conductivity, 
, for normalizing the conductivity
