According to Joule’s law, if the potential difference across a conductor having a material of specific resistance remains constant, then the heat produced in the conductor is directly proportional to

View answer and explanation

Correct option: D

\frac{1}{\rho }

Option D (

\frac{1}{\rho }

) is correct because, according to Joule's law, heat produced is inversely proportional to the specific resistance when the potential difference is constant.
