Creation of a galvanic cell requires the bucket type capacity, steel and copper plates. Flood the earth in a bucket with water and thrust in it plates - on their ends the potential difference will appear. For creation of more powerful element take a half-liter jar, fill up in it copper vitriol, lower copper and zinc electrodes. On them tension will also appear.
It is required to you
- steel and copper plate, copper wire, bank, bucket, zinc plate.
Instruction
1. The elementary galvanic you elementvozmit a usual bucket or a garbage plastic bag, fill it with the earth. Plentifully water the earth with the concentrated salt solution. The field of it thrust a steel and copper plate in this design. Having attached the voltmeter to conclusions of each of plates, it is possible to make sure that the potential difference is up to 1 volt. For increase in tension do most concentrated salt solution "that egg in it floated", and select plates so that their area was maximum. It is also the simplest galvanic cell.
2. To receive bigger tension, it is possible to make several galvanic cells and to connect from consistently. Then it is possible to connect the receiver or the charger for mobile phones to such battery. For increase in current connect elements in parallel.
3. Compact galvanic you elementvozmit to bank volume in half of liter. Fill not its bottom copper vitriol so that it completely closed a bottom. Take a soft copper wire and bend it so that the spiral which will lay down on a bottom banks was formed. Bend the end of this wire so that it left from banks and carefully insulate. It will be positive contact galvanicof element. In a cover banks build in a zinc plate, it is desirable that it was roundish, repeating a form banks. On a cover there has to be a conclusion to this plate and also an opening through which the copper wire will be removed by the isolated end.
4. Fill in water which will dissolve copper vitriol in bank, accurately mount the battery. A positive pole – a copper wire, negative – a zinc plate. As a result at sufficient compactness it long time will be able to give potential difference about 0.8 V, at currents 400 ma. For cheapening of a design instead of zinc it is possible to take aluminum, but the power of the battery will be less.
