Constantan wire is used in making standard resistances because its |
|
a) |
Specific resistance is low |
b) |
Density is high |
c) |
Temperature coefficient of resistance is negligible |
d) |
Melting point is high |

b) |
Density is high |
c) |
Temperature coefficient of resistance is negligible |
d) |
Melting point is high |
(c) Due to the negligible temperature co-efficient of resistance of constantan wire, there is no change in it’s resistance value with change in temperature |
