Question

dimension and unit of charge

Answer 1

 

The units of electric charge are defined as follows.

  

An abcoulomb is defined as 10 coulombs and is energy-equivalent to the unit square root centimeter square root gram (cmg−−−−√).

  

A statcoulomb is defined as 10c coulomb where c is the magnitude of the speed of light, and is energy-equivalent to the unit square root cubic centimeter square root gram per second (cm3/2g−√s).

  

An electron is the electric charge on an electron, or approximately 1.6021773310-19 coulomb.

  

A franklin is another name for a statcoulomb.

  

A planck charge is defined as the square root of: twice the planck constant times the speed of light times the permittivity of vacuum.
