• question_answer1) STATEMENT - 1 The temperature dependence of resistance is usually given as\[R={{R}_{0}}(1+\alpha \,\,\Delta t)\]. The resistance of a wire changes from\[100\,\Omega \]to \[150\,\Omega \] when its temperature is increased from\[27{}^\text{o}C\]to\[227{}^\text{o}C.\] This implies that\[\alpha =2.5\]\[\times {{10}^{3}}/{}^\text{o}C.\] STATEMENT - 2 \[R={{R}_{0}}(1+\alpha \text{ }\Delta t)\]is valid only when the change in the temperature DT is small and\[\Delta R=(R{{R}_{0}})<<{{R}_{0}}.\]     AIEEE  Solved  Paper-2009
