Question

Two conductors have the same resistance at $0^{\circ} C$ but their temperature coefficient of resistanc are $α_{1} and α_{2} .$ The respective temperature coefficients of their series and parallel combinations are nearly

\frac{α _{1} + α _{2}}{2}, α_{1} + α_{2}

α_{1} + α_{2}, \frac{α _{1} + α _{2}}{2}

α_{1} + α_{2}, \frac{α _{1} α _{2}}{α _{1} + α _{2}}

\frac{α _{1} + α _{2}}{2}, \frac{α _{1} + α _{2}}{2}
