MCQ
Which among the following has weak temperature dependence values with resistivity?
  • A
    Silver
  • B
    Copper
  • Nichrome
  • D
    Germanium

Answer

Correct option: C.
Nichrome

Alloys have high resistivity. The resistivity of nichrome has weak temperature dependence. At absolute zero, a pure metal has negligibly small resistivity while an alloy like nichrome has some residual resistivity.
