Two rods A and B are of equal length. Each rod has the ends at temp `T_(1)` and `T_(2)` . What is the condition that will ensure equal rates of flow of heat through the rods A and B ?

Explanation

To determine the condition that ensures equal rates of heat flow through two rods A and B, we can use the formula for heat conduction, which is given by Fourier's law of heat conduction. The rate of heat flow (Q/t) through a rod can be expressed as:

\[ \frac{Q}{t} = \frac{k \cdot A \cdot (T_1 - T_2)}{L} \]

where:
- \( Q \) is the amount of heat transferred,
