An aluminum fin is attached to a transistor that generates heat at the rate of 300mW. The fin has a total surface area of 9.0cm2 and is exposed to surrounding air at 27C. The contact conductance between transistor and fin is 0.9104m2.C/W, and the contact area is 0.5cm2. Estimate the temperature of the transistor, assuming the fin is uniform in temperature (TB1, Problem 2.116) [Ans: T=27.54C]
