Question

In the thermal resistance analogy to Ohm’s law, which expression correctly matches the electrical form I = V/R?

Options

• P_cond​ = (T₁ − T₂)R_T

• R_T ​= P_cond​ / (T₁​ − T_2​)

• P_cond​ = (T₁​ − T₂​) / R_T​

• T₁​ − T₂ ​= P_cond​R_T​

Answer 1

P_cond​ = (T₁​ − T₂​) / R_T

Explanation:

In the heat-flow analogy, temperature difference acts like voltage, and heat flow equals temperature difference divided by thermal resistance.
