Vedclass · Answer

(C) Standard resistors are designed to maintain a constant resistance value over a wide range of temperatures. For a material to be suitable for a standard resistor, its resistance should not change significantly with temperature. The temperature coefficient of resistance $(\alpha)$ for such materials must be very low or negligible. Tungsten is often used in specific applications, but for standard resistors, alloys like Manganin or Constantan are typically preferred because they have a very low temperature coefficient of resistance. However, in the context of this specific question, the property that makes a material suitable for a standard resistor is that its resistance remains stable, which implies a negligible temperature coefficient of resistance.
