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$=\frac{l}{K A}=\left[\frac{L}{M L T^{-3} K^{-1} \times L^2}\right]=\left[M^{-1} L^{-2} T^3 K\right]$
