MCQ
The dimensional formula for thermal resistance is
- ✓$M^{-1} L^{-2} T^3 \theta$
- B$M^{-1}L^{-2}T^{-3} \theta$
- C$ML^{2} T^{-2} \theta$
- D$ML^{2} T^2 \theta^{-1}$
✓
Answer
Correct option: A.
$M^{-1} L^{-2} T^3 \theta$
a
$\frac{{{\text{dH}}}}{{{\text{dt}}}} = \frac{{{T_1} - {T_2}}}{R}\,\,\,\,\,\,\,\frac{{M{L^2}{T^{ - 2}}}}{T} = \frac{\theta }{R}$
$\frac{{{\text{dH}}}}{{{\text{dt}}}} = \frac{{{T_1} - {T_2}}}{R}\,\,\,\,\,\,\,\frac{{M{L^2}{T^{ - 2}}}}{T} = \frac{\theta }{R}$
