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 exactly ccgs 10−8 volt, i.e. to 299.792458 volts. The statvolt is also defined in the CGS system as 1 erg / statcoulomb. It is a useful unit for electromagnetism because, in a vacuum, an electric field of one statvolt per centimetre 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. In the CGS-EMU system, the unit of voltage is the abvolt. (Wikipedia).
What is a (mathematical) model?
"Model" is a vague term that means different things in different contexts. Here I clear it all up in the context of statistics! For a complete index of all the StatQuest videos, check out: https://statquest.org/video-index/ If you'd like to support StatQuest, please consider... Buying T
