Mention the key scientists contributed in the following realizations and list the years: 1- Electric charges (positive and negative) 2- Coulomb's law 3- Electric field 4- Gauss's law Type your answer and keep everything to less than 200 words.

1- Electric charges (positive and negative) - Benjamin Franklin  in 1742.

2- Coulomb's law: Charles Augustin Coulomb from 1764 to 1772.

3- Electric field:    Michael Faraday -  1821

4- Gauss's Law: Joseph Louis Lagrange was the first to formulate the rule in 1773, followed by Carl Friedrich Gauss in 1867.

Explanation:

The Electric charge: In 1742, an American orator and inventor named Benjamin Franklin designed the positive and negative values of the charge.

Coulomb's law: The theory was first published in 1785 by Charles Augustin de Coulomb, a French physicist who was instrumental and prominent in the advancement of electromagnetism theory.

Gauss Law: Carl Friedrich Gauss developed this law in 1835. It was not released until 1867, However, Classical electrodynamics is based on this law.
