Q.

Which of the following is the correct relationship between thermal resistance and thermal conductivity?

A. r = k/l
B. r = k.l
C. r = l/k
D. r = l2/k
Answer» C. r = l/k
Explanation: thermal resistance and thermal conductivity are related by the equation r = l/k. here, r is the thermal resistance, k is the thermal conductivity and l is the thickness. thermal resistance is the reciprocal of thermal conductance.
