The Bagdad Battery

 As everyone knows, the electric cell was first invented by Alexander Volta around the 19th century. Before he invented an electric cell, that is, about 2000 years ago, a Vishnu civilization had created a battery to generate electricity or for some other purpose. In any case, the construction of an electric cell in this way, without any chemical or other knowledge, may have happened due to some coincidence or on the basis of some knowledge.

The Bagdad Battery

In 1938, Wilhelm Kotig, a German archeologist, found a lot of specially shaped clay pots in an area called Bujut Rabu near Baghdad, Iraq. As a large number of identical pottery vessels were found, the researchers looked into this further. These bowls, which are made of clay and are about 13 cm high, have a hole of about 3 × 4 cm in the top, through which an iron awl embedded in a copper plate is fixed. The copper and iron hooves are made of a non-metallic material so that they do not interfere with each other.

This pot is known as Bagdad Battery or Parthian Battery. According to archaeologists, it was found near Bujuta Rabu in Iraq, near the Barnian (150 BC - 223 AD) or Sassanian (224 - 650 AD) empires, so it could belong to either of these two eras.

The origin and purpose of the Baghdad Battery is still unclear. Many more facts are needed to clarify the purpose of this. But unfortunately it is still not certain. Some researchers hypothesized that the object may have acted as a galvanic cell. Or that it may have been used for electrolysis or some form of electrotherapy. But as mentioned before, the purpose is unclear as the electronics of this era have not been folded into metallized goods. As an alternative explanation, it is said that this may have been used as a mrujusa where sacred writings were placed. But that is the purpose of the Baghdad battery It is clear that it is not.

Considering the performance of the Baghdad battery, it has the same performance as a modern car battery. That is, a weak acid solution is required for this to work. A certain electric current can be produced by using a weak acid inside the clay pot and connecting the copper and iron strips. Vinegar, lemon juice, orange juice can be used as a weak acid solution.

 

How the Bagdad battery produces electricity

Dr. Ma Jori Sendal, a professor of history of science and technology who conducted further research on this, says that this single battery can produce approximately 0.8 volts of electricity. But Professor Caddock says that if it was used to generate electricity, it would be possible to produce more voltage by connecting these pots in series, but there is no evidence that this was done, so the interpretation here is wrong. That is because the wires that connected these bins were not found. But he says he believes it's a battery.
