Why do we prefer alloys for making standard resistors?
Share
Alloys are preferred for standard resistors because they have high resistivity and low temperature coefficients of resistance. This ensures minimal variation in resistance with temperature changes, providing stability and accuracy. Alloys like manganin and constantan are commonly used for their durability and resistance to oxidation.
