Question

Heya❤





Write any two special characteristics of MANGANIN due to which it is used in making standard resistance. ​

Answer 1

Answer:

.They are used to making standard resistors because 1)they have a high value of resistivity.2)temperature coefficient of resistance is less.3)they are least affected by temperature. The standard resistances are made of manganin because of 1. The variation of resistivity with temperature is very small.

hope it will help you

thank you
