a$)$ Thermal resistance, electrical resistance.

b$)$ Temperature difference, voltage difference

c$)$ heat rate, current

$(2$ points$)$ What purpose is served by attaching fins to a surface? boundary conditions. Which fin will have higher efficiency: the one with a rectangular cross$-$section or the one with a triangular cross$-$section? Explain how you come to your answer.
