The simple electric column is the first in history invented chemical electric battery.
It was invented by the physicist Alessandro Volta in 1799. After his invention of the battery, Volta stated that the credit goes to William Nicholson, Tiberius Cavallo and Abraham Bennett.
This battery consists of two electrodes, one of which is zinc and the other is copper, and between them there is an electrolyte of sulfuric acid or a mixture of water and salt. Zinc has a higher order in the electrochemical chain than copper and hydrogen, so it reacts with positive sulfur and hydrogen bubbles appear on the copper electrode, taking some of its electrons. Thus, zinc becomes a negative terminal and copper a positive terminal. Thus, we have two terminals that produce an electric current when connected.
It was the beginning of generating electrical potential.
