A uniform rod of area $A$ and conductivity $k$ carries a thermal current $I$ with a temperature gradient $\frac{d T}{d l}$ . Which statements are correct?

Options:(select one or more)

Answer:

A, B, D

Solution:

$I = k A \frac{d T}{d l}$ . So $I \propto A$ , $I \propto \frac{d T}{d l}$ and $I \propto k$ . C is false. A, B and D.
