The thermal conductivity of a rod is \(2 .\) What is its thermal resistivity?
- A \(0.5\)
- B 1
- C \(0.25\)
- D 2
Answer & Solution
Correct Answer
(A) \(0.5\)
Step-by-step Solution
Detailed explanation
Key Idea Thermal resistivity is reciprocal of thermal conductivity.
\(
\begin{aligned}
\text {Thermal resistivity } &=\frac{1}{\text { Thermal conductivity }} \\
&=\frac{1}{2} \\
&=0.5
\end{aligned}
\)
\(
