Question

What causes the peltier effect between 2 metals?

Answer 1

In the Peltier effect, current through a2-metal junction will cause an increase or decrease in temperature as electrons traveling through 1 metal are higher in energy than metals in the other level, and the increase or decrease in electron energy crossing the junction will come out of or contribute to the thermal.

Answer 2

★Metaljunction increase or decrease the temperature of electron is the cause of peltier effect.

★As the electron where the smallest particle in atoms the executes more temperature and energy from it.


Hence, these are the two causes of the peltier effect between two metals
