Product Code: NELAB-26-A1012
The principle of the difference between the current and the current generated by the Temperature Difference Electricity Generator of the students in the teaching.
The middle part is provided with a refrigeration piece, and the middle part is provided with a refrigerator, and a small fan and two connecting posts are arranged in the middle of the two sheets.
The overall size is about: 56*58*255mm. With two transparent plastic cups. In the experiment, first turn on the switch of the small fan. Again in a cup of half a cup of hot water, another cup grand half cup of cold water or ice water.
The experimental device of the two aluminum pins into the cup, two aluminum heat conduction, began to form a temperature difference.
When the temperature difference between them is more than 12, the current of the electric current is enough to cause the small fan to rotate.
The greater the temperature difference, the greater the current generated. When the reverse experiment is done, turn off the small fan switch.
Then through the connecting column access to the current 3-6V, after a little over a period of time to touch the two aluminum legs, you can find two feet a fever, a lower temperature, the formation of temperature. This is the West Burke effect and Parr effect.
