MCQ
The dimensions of thermal resistance are
  • $M^{-1} L^{-2} T^3 K$
  • B
    $M L^2 T^{-2} K^{-1}$
  • C
    $M L^2 T^{-3} K$
  • D
    $M L^2 T^{-2} K^{-2}$

Answer

Correct option: A.
$M^{-1} L^{-2} T^3 K$
(a) Thermal resistance$=\frac{l}{K A}=\left[\frac{L}{M L T^{-3} K^{-1} \times L^2}\right]=\left[M^{-1} L^{-2} T^3 K\right]$
