The unit of electric resistance(symbol Ω). The ohm is the electric resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere.

The electric resistance unit in the CGS system of electromagnetic units (symbo abΩ). 1 abohm is the resistance
when the potential difference is 1 abvolt when a current is 1 abampere. One abohm equals 10^{-9} ohm.

The electric resistance unit in the CGS system of electromagnetic units, abohm (symbo abΩ).
1 abohm is the resistance when the potential
difference is 1 abvolt when a current is 1 abampere. One abohm equals 10^{-9} ohm.

The electric resistance unit in the CGS system of electrostatic units, statohm (symbo statΩ).
1 statohm is the resistance when the potential difference
is 1 statvolt when a current is 1 statampere. One statohm equals 8.987552 x 10^{11} ohm.
