Q. The alloys constantan and manganin are used to make standard resistance became they have
Current Electricity
A
high resistivity
13%
B
low temperature coefficient of resistance
4%
C
low resistivity
0%
D
both (a) and (b)
83%
Solution:
Alloys how low value of temperature coefficient (less temperature sensitivity of resistance and high resistivity).
