the Bagdad Battery

The Baghdad Battery is an artifact discovered in Iraq that resembles a simple galvanic cell, potentially used for electrochemical experiments. It consists of a clay jar, a copper cylinder, and an iron rod, which could generate a small electric current when filled with an electrolyte like vinegar or lemon juice. Some researchers speculate it might have been used for electroplating or other electrical applications in ancient times, though definitive evidence of its purpose remains elusive. Its significance lies in its potential to show early knowledge of electricity, challenging previous assumptions about technological development in ancient civilizations.
