A potential difference of 1 abV will drive a current of one abampere
Abampere
The abampere , also called the biot after Jean-Baptiste Biot, is the basic electromagnetic unit of electric current in the emu-cgs system of units . One abampere is equal to ten amperes in the SI system of units...

 through a resistance of one abohm
Abohm
The abohm is the basic unit of electrical resistance in the emu-cgs system of units . One abohm is equal to 10-9 ohms in the SI system of units; one abohm is a nanoohm....

.

In most practical applications, the volt and its multiples are preferred. The national standard in the United States deprecates the use of the abvolt, suggesting the use of volts instead.

The other option in the cgs system is the statvolt
Statvolt
The statvolt is a unit of voltage and electrical potential used in the cgs system of units. The conversion to the SI system isIt 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...
