Abvolt

The abvolt (symbol abV) is the unit of electric potential difference (electromotive force) in the cgs-emu (centimeter-gram-second electromagnetic) system of units.

The abvolt is defined as the difference in electric potential between two points in a conductor carrying a constant current of 1 abampere ( = 10 A) when the power dissipated between them is equal to 1 erg ( = 10&minus;7 joule) per second. From
 * $$ \, P = i V $$

with power P in erg/s and electric current i in abA, we obtain by dimensional analysis
 * 1 abvolt = 1 erg/(s&sdot;abA) = 10&minus;7 J/(10&sdot;s&sdot;A) = 1&sdot;10&minus;8 J/C =  1&sdot;10&minus;8 volt.
