Statvolt
Encyclopedia
The statvolt is a unit of voltage
and electrical potential used in the cgs system of units. The conversion to the SI
system is
It is a useful unit for electromagnetism
because one statvolt per centimetre
is equal in magnitude to one gauss
. Thus, for example, an electric field
of one statvolt/cm has the same energy density as a magnetic field
of one gauss. Likewise, a plane wave propagating in a vacuum has perpendicular electric and magnetic fields such that for every gauss of magnetic field intensity there is one statvolt/cm of electric field intensity.
The abvolt
is another option for a unit of voltage in the cgs system.

Centimetre
A centimetre is a unit of length in the metric system, equal to one hundredth of a metre, which is the SI base unit of length. Centi is the SI prefix for a factor of . Hence a centimetre can be written as or — meaning or respectively...

Gauss (unit)
The gauss, abbreviated as G, is the cgs unit of measurement of a magnetic field B , named after the German mathematician and physicist Carl Friedrich Gauss. One gauss is defined as one maxwell per square centimeter; it equals 1 tesla...

Magnetic field
A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude ; as such it is a vector field.Technically, a magnetic field is a pseudo vector;...

Abvolt
The abvolt is one option for the unit of potential difference in the CGS system of units, and is equal to 10−8 volts in the SI system.A potential difference of 1 abV will drive a current of one abampere through a resistance of one abohm....
