Final answer:
The relationship between the initial and final values of current and temperature can be determined using the equation KA(T2-T1) for heat transfer by conduction.
Step-by-step explanation:
To determine the relationship between the initial and final values of the current (i0 and i) and the initial and final temperatures (t0 and t), we need to use a specific equation. From the given information, we can infer that the equation KA(T2-T1) is appropriate.
This equation relates the rate of heat transfer by conduction to the thermal conductivity (K), surface area (A), and the temperature difference (T2-T1).
