Definitions of units for electric potential

abvolt

The electric potential unit in the CGS system of electromagnetic units (symbol abV). 1 abvolt is one erg of energy per abcoulomb (1 abC) of charge, which will drive a current of one abampere (1 abA) through a resistance of one abohm (abΩ ). One abvolt is equal to 10-8 volt.

statvolt

The electric potential unit in the CGS system of electrostatic units (symbol statV). 1 statvolt is one erg of energy per statcoulomb (1 statC) of charge, which will drive a current of one statampere (1 statA) through a resistance of one abohm (statΩ ). One statvolt is equal to about 299.79246 volt.

volt

Unit of potential difference or of electromotive force (symbol V). I is the potential difference between two points of a conducting wire carrying a constant current of 1 ampere, when the power dissipated between these points is equal to 1 watt.
