The two ends of a rod of length ' $x$ ' and uniform cross-sectional area ' A ' are kept at temperatures ' $\mathrm{T}_1$ ' and ' $\mathrm{T}_2$ ' respectively ( $\mathrm{T}_1>\mathrm{T}_2$ ). If the rate of heat transfer is ' $\mathrm{Q} / \mathrm{t}$ ', through the rod in steady state, then the coefficient of thermal conductivity ' K ' is

$\frac{A Q}{\operatorname{tx}\left(T_1-T_2\right)}$

$\frac{x Q}{t A\left(T_1-T_2\right)}$

$\frac{x A Q}{t\left(T_1-T_2\right)}$

$\frac{Q}{\operatorname{txA}\left(T_1-T_2\right)}$
