Everyday life, often seen with ordinary dry batteries, button cells, batteries of cell phones, but you think that the fruit may also produce electricity do? In fact, using fruits and vegetables is also possible to produce electricity.
Production of magic as follows: kd186, y9943, fk890, gk479
1. If the first fruits and repeatedly rubbing pressure, undermining its internal organization, fruits and vegetables can choose to use grapefruit, lemons, oranges, potatoes, apples and so on.
2. Copper as the anode of the battery, the cathode of aluminum and put them under the threshold of 2 cm × 3 cm strips. Because the surface of copper and aluminum oxidize in May, so first floor on the oxide surface with sandpaper.
3. Copper and aluminum insert in the product (copper and aluminum in the fruit that should not be met), with the wire will be aluminum, copper, respectively, and connect a voltmeter to ensure the son and aluminum, copper plates well. If this tension is not large enough, can be linked together in the same kinds of fruit. vgp-bps2b ,vgp-bps2c
4. Experimental results: the cells of the fruit can actually generate electricity, but the difference in electricity less convenient.
5. Principles of interpretation: When the copper, tomatoes and sour aluminum insert and other fruits and vegetables, after which the acid reacts with aluminum. After the loss of some aluminum electronics, it produces a potential difference between copper (eg voltage). When the two pole pieces of a wire connected to the ammeter, they form a closed circuit. If the number of fruit in the whole series, and then connect the light-emitting diodes, light emitting diodes may be illuminated.
This method is widely used in education is to enable students to understand the structure of cells, a preliminary understanding of the fruit battery works to improve their practice. Students can learn by experiment 1. Understanding of power, knowing the battery category. 2. Know that the body of the safe voltage, alternating current of all by how much. 3. Institute for the safe use of electricity. 4. Learn how to make fruit and vegetables from the farm. pa3400u-1brs , pa3420u-1brs
However, in everyday life, if each of us get inspiration through a number of principles will be able to do some intelligent use of resources, canals, and better economy of energy!
