  2. Coulomb - Wikipedia

    en.wikipedia.org/wiki/Coulomb

    The coulomb is named after Charles-Augustin de Coulomb. As with every SI unit named for a person, its symbol starts with an upper case letter (C), but when written in full, it follows the rules for capitalisation of a common noun; i.e., coulomb becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case. [9]

  4. Coulomb's law - Wikipedia

    en.wikipedia.org/wiki/Coulomb's_law

    Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest. This electric force is conventionally called the electrostatic force or Coulomb force . [ 2 ]

  5. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]

  6. List of physical constants - Wikipedia

    These include the Boltzmann constant, which gives the correspondence of the dimension temperature to the dimension of energy per degree of freedom, and the Avogadro constant, which gives the correspondence of the dimension of amount of substance with the dimension of count of entities (the latter formally regarded in the SI as being dimensionless).

    symbol If set to yes, the value is preceded by the symbol of the constant, followed by ≈ or = depending on whether round is set. round If omitted, the value is shown along with its standard uncertainty.

  9. Elementary charge - Wikipedia

    en.wikipedia.org/wiki/Elementary_charge

    In the SI system of units, the value of the elementary charge is exactly defined as = 1.602 176 634 × 10 −19 coulombs, or 160.2176634 zeptocoulombs (zC). [3] Since the 2019 revision of the SI , the seven SI base units are defined in terms of seven fundamental physical constants, of which the elementary charge is one.
