Both $(B)$ and $(C)$

Vedclass · Answer

(D) Standard resistors are designed to maintain a constant resistance value regardless of changes in temperature. Constantan and manganin are alloys that exhibit two key properties: $1$. They have high resistivity,which allows for the construction of compact resistors. $2$. They have a very low temperature coefficient of resistance,meaning their resistance changes negligibly with temperature fluctuations. Therefore,both properties make them ideal for standard resistance. Thus,the correct option is $(D)$.

The alloys constantan and manganin are used to make standard resistance due to they have
