The alloys constantan and managing are used to make standard resistance due to they have
Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: Understand the properties of constantan and manganin.
Step 2: Constantan has a relatively low temperature coefficient of resistance, which makes it stable under varying temperatures.
Step 3: Manganin also exhibits a low temperature coefficient of resistance, making it ideal for precision resistors.
Step 4: Both alloys have low temperature coefficients, which is crucial for making standard resistance.
Therefore, the correct answer is C.
