26.
As per Matthiessen's rule, the total resistivity r of a conductor can be written as r = ri + aT, where ri and a are constants and T is absolute temperature. At very low temperatures
Answer: Option
Explanation:
At very low temperatures a T → 0. Since resistivity has a finite value even at low temperature, a T < ri.
