One faraday of charge is the charge of one mole of elementary charges (or of negative one mole of electrons), that is, 1 faraday = F × 1 mol = 9.648 533 212 331 001 84 × 10 4 C. Conversely, the Faraday constant F equals 1 faraday per mole. The faraday is not to be confused with the farad, an unrelated unit of capacitance (1 farad = 1 coulomb ...

In terms of the Avogadro constant (N A), one coulomb is equal to approximately 1.036 × 10 −5 mol × N A elementary charges. Every farad of capacitance can hold one coulomb per volt across the capacitor. One ampere hour equals 3600 C, hence 1 mA⋅h = 3.6 C.
The principal U(1)-connection ∇ on the line bundle has a curvature F = ∇ 2, which is a two-form that automatically satisfies dF = 0 and can be interpreted as a field strength. If the line bundle is trivial with flat reference connection d we can write ∇ = d + A and F = d A with A the 1-form composed of the electric potential and the ...
Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal nĚ‚, d is the dipole moment between two point charges, the volume density of these is the polarization density P.
The farad (symbol: F) is the unit of electrical capacitance, the ability of a body to store an electrical charge, in the International System of Units (SI), equivalent to 1 coulomb per volt (C/V). [1] It is named after the English physicist Michael Faraday (1791–1867). In SI base units 1 F = 1 kg −1 ⋅m −2 ⋅s 4 ⋅A 2.

The first term in the formula for represents the Coulomb's law for the static electric field. The second term is the time derivative of the first Coulombic term multiplied by r ′ c {\displaystyle {\frac {r'}{c}}} which is the propagation time of the electric field.
