Two ends of area $A$ of a uniform rod of thermal conductivity $k$ are maintained at different temperatures. At any point on the rod, the temperature gradient is $\frac{d T}{d l}$ . If $I$ be the thermal current in the rod, then:

Options:(select one or more)

Answer:

A, B

Solution:

$I = k A \frac{d T}{d l}$ in magnitude, so $I \propto A$ and $I \propto \frac{d T}{d l}$ . A and B.
