Calculated the proportion between electrodynamic and electrostatic units, producing a value very close to the speed of light.

In electrostatic units, electrical charge is defined by the force that it exerts on other charges.

One form was developed for electrostatic units and another for electromagnetic units.

The electrostatic units of measure are now known as the statampere, the statvolt, the statcoulomb and so on.

The main electrostatic units are:

The electrostatic unit (esu) of electrical charge (also known as the "Statcoulomb")

Electrostatic units or Gaussian units.

Others include "electrostatic units", "electromagnetic units", and Lorentz-Heaviside units.

Electrostatic units (ESU)

Optimal performance is achieved when system air filters are clean, and a homeowner should change / clean filters (except electrostatic units) at least once a month.

This led to his prediction that electromagnetic waves existed and would propagate at a velocity c equal to the ratio of electromagnetic to electrostatic units of measurement.

These are generally either thermal or electrostatic units which tend to offer a cheaper solution than buying an interface and a good quality matrix printer but the results obtained tend to be less professional.

In one variant of the CGS system, Electrostatic units (ESU), charge is defined via the force it exerts on other charges, and current is then defined as charge per time.

Electromotive force in electrostatic units is the statvolt (in the centimeter gram second system of units equal in amount to an erg per electrostatic unit of charge).

Others range from metal honeycomb types for commercial cooking hoods up to the extremely high efficiency HEPA/Absolute type used in operating theatres, and the electrostatic units often found in high quality office buildings.

In 1856 Wilhelm Eduard Weber and Rudolf Kohlrausch performed an experiment to measure the numerical value of the ratio of the electromagnetic unit of charge to the electrostatic unit of charge.

The roentgen (R) is an obsolete traditional unit of exposure, which represented the amount of radiation required to create one electrostatic unit of charge of each polarity in one cubic centimeter of dry air.

Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10 statcoulomb (generally called e.s.u. (electrostatic unit) in older literature), which were separated by 1 ångström.

GOST standard 7623 defined it as "the physical dose of X-rays which produces charges each of one electrostatic unit in magnitude per cm of irradiated volume in air at 0 C and normal atmospheric pressure when ionization is complete."

The Gaussian system of units was based on Heinrich Hertz realization, made in 1888 while verifying Maxwell's Equations, that the CGS system of electromagnetic units to were related to the CGS system of electrostatic units by the relationship:

He was then appointed for one year preparer physics laboratory of the Ecole Normale Superieure, then led by Jules Violle, where he wrote his thesis for the doctorate in physical sciences: "New determination of the ratio between electromagnetic and electrostatic units", which he received in 1892.

In the year 1856, Wilhelm Eduard Weber and Rudolf Kohlrausch measured the ratio of the electromagnetic and electrostatic units of charge, 1/ ε'μ, by discharging a Leyden jar, and found that its numerical value was very close to the speed of light as measured directly by Fizeau.

Although the CGS units have mostly been supplanted by the MKSA (meter-kilogram-second-ampere) or International System of Units (SI) units, the electrostatic units are still in occasional use in some applications, most notably in certain fields of physics such as in particle physics and astrophysics.
