Question

Q. The dimensional formula for thermal resistance is
$$\begin{gathered} 1.M^{-1}{L}^{-2}{T}^3\theta \\ 2.M^{-1}{L}^{-2}{T}^{-3}\theta \\ 3.M{L}^2{T}^{-2}\theta \\ 4.M{L}^2{T}^2{\theta }^{-1} \end{gathered}$$

Answer 1

Dear Student ,
The dimensional formula for thermal conductivity is = $\left[ML{T}^{-3}{\theta }^{-1}\right]$
So the dimension of thermal resistance is = $\left[M^{-1}{L}^{-2}{T}^{-3}\theta \right]$
