Principle
In this experiment, the shown effect in experiment 7.1 is
inverted. Instead of converting heat into electric energy with the
help of the thermo generator, we prove here the Peltier effect. The
effect is that the current flowing through the Peltier element
heats one plate up and cools down the other. The higher the
current, the faster the plates will heat up or cool down.
A beaker with water is situated on the Peltier element of the
thermo generator. If someone lets current flow in this Peltier
element while it is set at the correct polarity, the upper plate of
the Peltier element cools the water down.
Benefits
- Experiment is part of a complete solution set with a total of
17 experiments for Renewable Energy Basics and Heat energy
