Joule effect is irreversible,whereas Peltier effect is reversible.

Vedclass · Answer

(D) The Joule effect refers to the heating of a conductor when an electric current passes through it,given by $H = I^2Rt$. This process is irreversible because the heat generated is dissipated into the surroundings and cannot be converted back into electrical energy simply by reversing the current.The Peltier effect refers to the production or absorption of heat at the junction of two dissimilar metals when an electric current flows through them. This effect is reversible; if the direction of the current is reversed,the heat that was previously absorbed will be released,and vice versa.Therefore,the Joule effect is irreversible,while the Peltier effect is reversible.
