The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). [1][2] It is equal to the electric charge delivered by a 1 ampere current in 1 second and is defined in terms of the elementary charge e, at about 6.241 509 × 1018 e. [2][1]
Το Κουλόμπ (Αγγλ. Coulomb) είναι η μονάδα μέτρησης ηλεκτρικού φορτίου και το σύμβολό της είναι το C. Το όνομά της το πήρε από τον διακεκριμένο Γάλλο φυσικό Σαρλ Ογκουστίν ντε Κουλόμπ.
28 Σεπ 2024 · Coulomb, unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units. It is abbreviated as C. The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere.

inversely proportional to square of the separation between their centers (r) directed along the separation vector connecting their centers (r̂) This relationship is known as Coulomb's Law. Charles-Augustin Coulomb (1736–1806) France. As an equation it is usually written in one of two forms…. F = k.
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects. In equation form, Coulomb's law can be stated as.
The SI derived unit of electric charge is the coulomb (C) named after French physicist Charles-Augustin de Coulomb. In electrical engineering it is also common to use the ampere-hour (A⋅h). In physics and chemistry it is common to use the elementary charge (e) as a unit.
