      TO CONSTRUCT TO A BATTERY DE VOLTA

THAT IT IS NEEDED

Copper pieces
Pieces of zinc or galvanized calamine
Heavy fabric pieces

A LED

Wire of conección

 

1. It places a zinc piece squared on a piece of fabric and these on the copper squared one, as it is seen in the illustration. With this or we have a battery of volta or pounds electrochemistry. each of these batteries has a voltage of 1 v but the current is very small

2. In order to be able to ignite a LED we will need to pile up several zinc layers, fabric and copper, as it is seen in the illustration.

3. The zinc or galvanized calamine is the negative terminal or anode and the copper are the positive terminal or cathode. So that the battery works you must wet water fabrics with salt. Soon the terminals of the LED are connected.

THAT IT IS WHAT IT HAPPENS

Volta constructed the first battery, according to his own description, preparing certain number of zinc and copper discs along with soaked cardboard discs in a salt water dissolution. Later he piled up these discs beginning by anyone of the metalists, for example one of copper, and on this one one of zinc, on which he placed one of wet discs and later one of copper, and so on until forming a column or “pounds?. When connecting some metallic strips to both ends were able to obtain sparks.
