Thermal conductivity of the conductor shown in figure is K. Find thermal resistance between points a and b.
.

Text Solution

Verified by Experts

From a to b area of cross -section perpendicular to ab is uniform `(A=xy)` and length along ab is z. Therefore, using the formula.
`R = l/(KA)`, we have
`R = z/(Kxy)` .
