When a current of

\mathrm{1}\,\,\mathrm{ampere}

is passed through a conductor whose ends are maintained at temperature difference of

1\,{\,^0}\mathrm{C}

, the amount of heat evolved or absorbed is called

View answer and explanation

Correct option: B

Thomson coefficient

Option B (Thomson coefficient) is correct because the Thomson coefficient describes the heat evolved or absorbed when a current passes through a conductor with a temperature gradient.
