Two conductors have the same resistance at 0℃ but their temperature coefficients of resistance are α1 and α2. The respectively temperature coefficients of their series and parallel combinations are nearly
- \(\frac{\mathbf{x}_{1}+\mathbf{x}_{2}}{2}, \mathbf{x}_{1}+\mathbf{x}_{2}\)
- \(\frac{x_{1}+x_{2}}{2}, \frac{x_{1}+x_{2}}{2}\)
- \(x_{1}+x_{2}, \frac{x_{1}+x_{2}}{2}\)
- \(\mathrm{x}_{1}+\mathrm{x}_{2}, \frac{\mathrm{x}_{1} \mathrm{x}_{2}}{\mathrm{x}_{1}+\mathrm{x}_{2}}\)
Answer
(B) x_ 1 +x_ 2 2 , x_ 1 +x_ 2 2
