hey guys .... in the sedtion we took if you have an infinite heat sink .. the thermal resistance between ( sink and air ) is equal to zero ................
well , thats not correct .. according to page 1253 in sedra (5th edition ) , look at the example ............... it clearly says .. " for an infinite heat sink , the total thermal resistance between case and air " theta ca ", is equal to ZERO , not just from sink to air .
thank you
