To produce electricity in house conditions, any difficult and smart devices are not necessary. Being guided by the simplest laws of physics known from a school course, and having a few improvised materials, it is possible to achieve desirable result easily. Vegetables and fruit - here an elementary source of electricity.
It is required to you
- - two copper plates (electrodes);
- - two copper or aluminum wires;
- - voltmeter.
Instruction
1. One of sources of electricity are ordinary phone lines. In them tension which not only provides operability of telephone sets of users is supported, but also allows to ensure functioning of the glow lamp of small and medium power.
2. Other known way of receiving electricity is its getting from a tree. That to make it, you will need two small pieces of metal. In interaction with each other these plates will form heteropolar electrodes - the anode and the cathode. Take one of them (for example, an iron nail or an aluminum core) and thrust it as it is possible more deeply in a tree trunk. Insert the second galvanic cell on 15-20 cm into the soil near a tree. Several seconds later between elements there will be tension in 1 Volt. In order that the developed tension had rather high quality, it is necessary to insert bigger quantity of cores into a tree.
3. The same way it is possible to receive electricity, having inserted galvanic cells into a lemon, orange and an other citrus. Moreover, in this case, besides copper and aluminum, it is also allowed to use plates (cores) from gold or silver by means of which it will be possible to receive tension size not in one, and in the whole two volts.
4. On the seasonal dacha it is possible to get electricity by means of ordinary crude potato. For this purpose, besides the tuber of potato, you will be need toothpaste, salt and wires. Take a tuber and cut it on two half. In the center of one of them a teaspoon make small deepening and put the toothpaste mixed with salt there, and through another carry out the smoothed-out wire. After that connect halves by means of matches, needles or toothpicks so that the wire adjoined to toothpaste. On it all - your source of electricity is ready to work. Now you with its help can include bulbs and from an electric spark to light fires.
