MCQ
For making standard resistance, wire of following material is used:
  • A
    Nichrome
  • B
    Copper
  • C
    Silver
  • D
    Manganin

Answer

  1. Manganin

Explanation:

Manganin is used to make standard resistors because

  1. They have high value of resistivity.
  2. Temperature coefficient of resistance is less.
  3. They are least affected by temperature.
