In the 9th edition From, in the SI units,

In the SI system of units, elementary charge is defined as a fundamental constant (effective from 20 May 2019). When expressed in the SI unit for electric charge (coulomb), the value for elementary charge is exactly.

The Sun is pretty big, but the Moon is not so big. The Sun is also quite hot.

Watson and Faraday
There is some ambiguity about whether Watson formulated a model of charge as a single fluid prior to Franklin’s model. Watson, after seeing Franklin's letter to Collinson, claims that he has the same model as Franklin. Franklin had studied some of Watson's works prior to making his own experiments and analysis, which was probably significant for Franklin’s own theorizing. One physicist suggests that Watson first proposed a one-fluid theory, which Franklin then elaborated further and more influentially. A historian of science argues that Watson missed a subtle difference between his ideas and Franklin’s, so that Watson misinterpreted his ideas as similar to Franklin’s. In any case, there was no animosity between Watson and Franklin, and the Franklin model of electrical action, formulated in early 1747, eventually became widely accepted at that time.

In 1838, Faraday raised a question about whether electricity was a fluid or fluids or a property of matter, like gravity. He investigated whether matter could be charged with one kind of charge independently of the other. He came to the conclusion that electric charge was a relation between two or more bodies, because he could not charge one body without having an opposite charge in another body.

Coulomb
Coulomb's law, or Coulomb's inverse-square law, is a law of physics for quantifying the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. The quantity of electrostatic force between stationary charges is always described by Coulomb’s law. The law was first published in 1785 by French physicist Charles-Augustin de Coulomb, and was essential to the development of the theory of electromagnetism, because it was now possible to discuss quantity of electric charge in a meaningful way

From "electricity" -- can work this into the formulation in next to last paragraph. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field.

Electric charge is a property of matter. There is only one kind of electric charge – according to contemporary, widely accepted physical theory (Standard Model).

Electric charge is carried by subatomic particles (such as protons, electrons, ions, muons). Empirical observation supports the fact that charged particles can be divided into two categories, positive or negative. All charges in the same category repel each other, and attract all charges in the other category. In abbreviated form: Like charges repel and unlike attract. The "thing" that carries this interaction is called charge.

The smallest quantity of electric charge that can exist freely is called the elementary charge, e. The quantity or amount of charge for a given particle or region can be zero, positive, or negative. A particle or object with no net charge is referred to as neutral. In ordinary matter, positive charge is carried commonly by the protons in the nuclei of atoms. All protons have a charge of +e. In ordinary matter, negative charge is carried commonly by electrons, which all have a charge of −e. Other subatomic particles can also carry positive charge (e.g., cations, positive muons, positive pions ) or negative charge (e.g., anions,negative muons , negative pions ).

Electric charge is quantized. That is, the amount of charge in an object or subatomic particle only appears in integer multiples of e, the elementary charge. (Particles called quarks are theorised to have charges less than e, but always appear in combinations that are at least e or a multiple of e).

Electric charge is a conserved property. The total charge of an isolated system (i.e., the algebraic sum of the positive charge and negative charge present in the system) cannot change. If the total charge is positive, then the object is said to be positively-charged. If the total charge is negative, then the object is said to be negatively-charged. If the amount of positive charge and negative charge is equal, then the object is said to be neutral.

Electric charges create an electric field, if they are moving they also generate a magnetic field. The combination of the electric and magnetic field is called the electromagnetic field. The interaction of the field with electric charges is the source of the electromagnetic force. An electromagnetic force is always present when an electric charge interacts with the electromagnetic field. The electromagnetic force is one of the four fundamental forces in physics. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects. The study of charged particles, and how their interactions are mediated by photons, is called quantum electrodynamics.

Different measurement units are used to express the value of e and electric charge. The SI derived unit of electric charge is the coulomb (C). The value for e is $1.602 coulombs$. In electrical engineering, it is also common to use the ampere-hour (Ah). In chemistry, it is common to use the elementary charge e as a unit. Chemistry also uses the Faraday constant as the charge on a mole of electrons. The symbol Q (or q) often denotes charge.

Legal ohm
In October 1882 in Paris, the "International Conference for the determination of electrical units" rejected the B.A. ohm, because of doubt about its accuracy, and issued a resolution that there was insufficient agreement to specify a value for the ohm, based on measurements of a column of mercury. The French government was asked to make available standards of resistance that could be used for further research.

A second session of the "International Conference" was held at Paris in 1884. In April and May, resolutions were issues that a legal ohm, a reproducible standard, was defined by the as the resistance of a mercury column of specified weight, 106 cm long and 1mm2 in cross-section; this was a compromise value between the B. A. unit (equivalent to 104.7 cm), the Siemens unit (100 cm by definition), and the CGS unit. This standard was to be communicated to national Governments for adoption. The "legal" system though was only to remain in force for 10 years, so that it would not prejudice future systems. Although called "legal", this standard was not adopted by any national legislation.
