Q. Nichrome or Manganin is widely used in wire bound standard resistors because of their

Solution:

Temperature coefficient of resistance of alloys have small values. Hence, resistivity of alloys depends weakly on temperature. Nichrome and manganin both are alloys and their resistivity depends weakly on temperature. Hence, they are used in wire bound standard resistors.
