One of the foremost experts on electricity in the 18th century was Benjamin Franklin, who argued in favour of a one-fluid theory of electricity.

Coulomb's law quantifies the electrostatic force between two particles by asserting that the force is proportional to the product of their charges, and inversely proportional to the square of the distance between them.

He discovered an inverse relationship of the force between electric charges and the square of its distance, later named after him as Coulomb's law.
Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs of nodes.
Some P system variants allow for a membrane to divide, possess a charge or have varying permeability by changing membrane thickness.
Such proton captures on stable nuclides (or nearly stable), however, are not very efficient in producing p-nuclei, especially the heavier ones, because the electric charge increases with each added proton, leading to an increased repulsion of the next proton to be added, according to Coulomb's law.
The versorium (Latin "turn around") was the first crude electroscope, the first instrument that could detect the presence of static electric charge.
Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force.
Liénard–Wiechert potential describes the electromagnetic effect of a moving electric charge
After some time the electric charge in the avalanche becomes so large that following Coulomb's law it generates an electric field as large as the external electric field.
This approach is commonly used by structural chemists and was defined by van der Waals when defining a region of space where the electric charge equipotential surface had a definite value.
