     A Power MOSFET has a rated power of 50W, The ambient temperature is given as 25 Celsius. If the maximum junction temperature is 105 Celsius, then determine the thermal resistance between the junction and the case   
  
  Solution
RESISTANCE=(DIFFERENCE BETWEEN TEMP)/(POWER DISPATED)
=(105-25)/50
1.6 Cel/W
