Question

When current is passed through a junction of two dissimilar metals, heat is evolved or absorbed at the junction. This process is called
(a) Seebeck effect
(b) Joule effect
(c) Petlier effect
(d) Thomson effect

Answer 1

petlier effect

please mark as branliest

Answer 2

When electricity passes through metal conductor,the metal conductor material gets heated due to it's specific electricial resistance.

Different conductor materials have different amounts of electricial resistance.

That's why in the junction of two conductor materials,the electricial flow creates or absorbs the heat in that junction portion.

And this phenomenon is also known as the "Petlier effect."

That's why the correct answer of this question is option C.
