the current and voltage probes, we estimate themeasurement error in the power and resistance to each be less than 1.5% over the entire range ofvalues plotted in Fig. 3. While the data was generated over the entire range of values of thecurrent, the plot has been truncated at a lower limit of 50mA of current. This ensures that thegraph reflects only the temperature range in which the radiative mechanism of power dissipationis dominant. Page 11.190.5The linearity of the plot is strong evidence that the temperature and resistance are related via apower-law of the form T ∝ R γ . From the slope of the line in Fig. 3 the value of γ is determined

following topics: Ü A view of E&M theory from a physics and engineering perspective Ü Sources of electromagnetic noise and shielding methods Ü Transmission line phenomena particularly with regard to high-speed digital system Ü General antenna theory and antenna propagation patterns; e.g. for cell phone applications and WiFi. Ü Basic plane wave phenomena such as reflection, transmission, and absorption characteristics at interfaces.Surprisingly, there was almost no external demand for our undergraduates to understand generalwave-guide theory. This was considered to be a more ‘advanced’ topic. With regard to appliedskills, a basic proficiency in the following was considered desirable. Ü Ability to perform E
