Peltier element
Have you ever heard of the term "Peltier element"? In fact, this Peltier element has a somewhat mysterious property that when electricity flows through it, one side becomes hot and the other side becomes cold. This may not sound very useful, but if you use it wisely, you can lower the temperature quite a bit. In this experiment, we will try to bring out the performance of the Peltier element to its limit. How low can we lower the temperature? We hope you enjoy it.
Seebeck effect
In the Peltier effect experiment, we talked about how the Peltier element becomes hot on one side and cold on the other when electricity flows through it. Now, let's think in reverse. What happens if we heat one side of the Peltier element and cool the other side? In this experiment, we will heat one side of the Peltier element with a hot plate and cool the other side with a cooler. Come and see for yourself what happens!
