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-A-aT = 0B-aT > riC-aT &sim; riD-aT < ri-D-aT < ri

Question

As per Matthiessen&#39;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-A-aT = 0B-aT &gt; riC-aT &sim; riD-aT &lt; ri-D-aT &lt; ri

APTITUDE CRACK · Accepted Answer

The correct option is  D aT &lt; ri At very low temperatures a T &rarr; 0. Since resistivity has a finite value even at low temperature, a T &lt; ri.
