If l is the length, A is the area of cross-section and K the thermal conductivity, then the thermal resistance of the block is given by

A metal rod of area of cross section A has length L and coefficient of thermal conductivity K the thermal resistance of the rod is .

" A metal rod of area of cross section A has length L and coefficient of thermal conductivity K The thermal resistance of the rod is "

If K is thermal conductivity then resisitivity will be-

The area of cross-section of rod is given by A= A_(0) (1+alphax) where A_(0) & alpha are constant and x is the distance from one end. If the thermal conductivity of the material is K . What is the thermal resistancy of the rod if its length is l_(0) ?
