WRITE TWO CHARACTERISTICS OF MANGANIN WHICH MAKES IT SUITABLE FOR MAKING STANDARD RESISTANCES.
The two important characteristics of manganin alloy that is useful in making standard resistance coils are:
- Manganin has a constant electrical resistance over a wide range of temperature that is a small value of temperature coefficients α and β . This makes it have same resistance even if resistance is heated up.
2. Manganin has a high resistivity.
