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

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 proportinal to
