Why are alloys used to make standard resistors?
(N/A) Alloys like Manganin or Constantan are used to make standard resistors because they have a very low temperature coefficient of resistance. This means that there is a negligible change in the resistance of an alloy with a change in temperature,ensuring that the resistance value remains stable even if the operating temperature fluctuates.
