A) temperature independent resistivity
B) very weakly temperature dependent resistivity
C) strong dependence of resistivity with temperature
D) mechanical strength
Correct Answer: B
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.
