The length of germanium rod is \(0.925 \mathrm{~cm}\) and its area of cross-section is \(1 \mathrm{~mm}^2\). If for germanium \(n_i=2.5 \times 10^{19} \mathrm{~m}^{-3}, \propto_n=0.19 \mathrm{~m}^2 / \mathrm{V}-\mathrm{s}, \propto_e=0.39 \mathrm{~m}^2 / \mathrm{V}\)-s, then the resistance of the rod is
