Two conductors have the same resistance at 0^{\circ} {\C} but their temperature coefficients of resistance are \alpha_1 and \alpha_2. The respective temperature coefficients of their series and parallel combinations are nearly [AIEEE 2010]

Correct Answer is : α1+α22,α1+α22

\frac{\alpha_1+\alpha_2}{2}, \alpha_1+\alpha_2

\alpha_1+\alpha_2, \frac{\alpha_1+\alpha_2}{2}

\alpha_1+\alpha_2, \frac{\alpha_1 \alpha_2}{\alpha_1+\alpha_2}

\frac{\alpha_1+\alpha_2}{2}, \frac{\alpha_1+\alpha_2}{2}
