The statcoulomb is defined as follows: If two stationary objects each carry a charge of 1 statC and are 1 cm apart in vacuum, they will electrically repel each other with a force of 1 dyne. From this definition, it is straightforward to find an equivalent charge in coulombs .

The statvolt is a unit of voltage and electrical potential used in the CGS-ESU and gaussian systems of units. In terms of its relation to the SI units, one statvolt corresponds to ccgs 10−8 volt, [a] i.e. to 299.792458 volts. [2] [b] The statvolt is also defined in the CGS system as 1 erg / statcoulomb. [2]

A capacitor of one farad can hold one coulomb at a drop of one volt. One ampere hour equals 3600 C, hence 1 mA⋅h = 3.6 C. One statcoulomb (statC), the obsolete CGS electrostatic unit of charge (esu), is approximately 3.3356 × 10−10 C or about one-third of a nanocoulomb.
The statcoulomb is defined as follows: if two objects each carry a charge of 1 statC and are 1 cm apart, they will repel each other with a force of 1 dyne. As a result, in the electrostatic cgs system, Coulomb's law describing the force F between two charges q1 and q2 a distance r apart takes the simple form: <math>F=\frac {q_1q_2} {r^2}</math>
Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10 −10 statcoulomb (generally called e.s.u. (electrostatic unit) in older scientific literature), which were separated by 1 ångström.
A lei de Coulomb é uma lei experimental [ 1] da física que descreve a interação eletrostática entre partículas eletricamente carregadas. Foi formulada e publicada pela primeira vez em 1783 pelo físico francês Charles Augustin de Coulomb e foi essencial para o desenvolvimento do estudo da eletricidade. [ 1]
Understanding the statcoulomb conceptually. Ask Question. Asked 5 years, 11 months ago. Modified 5 years, 4 months ago. Viewed 180 times. 1. I've just learned about the statcoulomb, which is basically a way to express charge when we didn't have units of charge (I think), with the definition.
