Who discovered positive charge?
In 1886 Eugene Goldstein (1850–1930) discovered evidence for the existence of this positively charged particle. Using a cathode ray tube with holes in the cathode, he noticed that there were rays traveling in the opposite direction from the cathode rays.

Where do positive and negative charges come from?
Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
Who said electrons have a negative charge?
J.J. Thomson’s
J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup.”
Who discovered negative charge?
J.J. Thomson’s discovery of the negatively charged electron had raised theoretical problems for physicists as early as 1897, because atoms as a whole are electrically neutral.
Who discovered Proton E Goldstein or Rutherford?
Proton
| The quark content of a proton. The color assignment of individual quarks is arbitrary, but all three colors must be present. Forces between quarks are mediated by gluons. | |
|---|---|
| Classification | Baryon |
| Discovered | Observed as H+ by Eugen Goldstein (1886). Identified in other nuclei (and named) by Ernest Rutherford (1917–1920). |
Who Named the charge?
Benjamin Franklin It was Franklin who named the two kinds of electricity ‘positive’ and ‘negative’. He even collected electric charges from thunderstorm clouds through wet string from a kite.
Who discovered electron?
J.J. Thomson
Although J.J. Thomson is credited with the discovery of the electron on the basis of his experiments with cathode rays in 1897, various physicists, including William Crookes, Arthur Schuster, Philipp Lenard, and others, who had also conducted cathode ray experiments claimed that they deserved the credit.
Who discovered proton?
Ernest Rutherford
It is 100 years since Ernest Rutherford published his results proving the existence of the proton. For decades, the proton was considered an elementary particle.
Who discovered protons?

What was Benjamin Franklin’s theory?
Franklin’s hypothesis is known as the “one-fluid” theory. He proposed that there exists an electrical fluid that can be found in all ordinary matter; it is positively charged (Franklin invents the word) and is self-repulsive, i.e, electrical fluid repels electrical fluid.
Who was the first scientist to discover electric charge?
What is electric charge? Benjamin Franklin was the first American scientist who proved that there are two types of electric charges: positive charge and negative charge. Electric charge is the property of sub-atomic particles particularly includes electrons and protons.
Who was the first person to choose positive or negative electricity?
The choice of which type of electricity is called “positive” and which “negative” was made around 1750 by Ben Franklin, early American scientist and man of many talents (the stamp on the left commemorates his role as first US postmaster–and colonial postmaster before that).
What was Franklin Franklin’s theory of electric charge?
Franklin was an advocate of a ‘single fluid’ model of electric charge. An object with an excess of fluid would have one charge; an object with a deficit of fluid would have the opposite charge. Other scientists had advocated a ‘two fluid’ theory, with separate positive and negative fluids moving around.
What is the difference between positive and negative electricity?
He thought that one kind signified a little excess of the “electric fluid” over the usual amount, and he called that “positive” electricity (marked by +), while the other kind was “negative” (marked -), signifying a slight deficiency.
