Definition:Abohm
Definition
The abohm is the CGS unrationalised electromagnetic unit of electrical resistance.
It is defined as being the electrical resistance between two points of an electrical conductor when a constant electric potential of $1$ abvolt, applied to these points, produces in the conductor an electric current of $1$ abampere, the conductor not being the seat of any electromotive force.
Symbol
- $\mathrm {ab \Omega}$
The symbol for the abohm is $\mathrm {ab \Omega}$, where $\Omega$ is the Greek letter Omega.
Its $\LaTeX$ code is \mathrm {ab \Omega} .
Also known as
The abohm is also known as the electromagnetic unit of resistance, abbreviated $\mathrm {e.m.u.}$.
Source of Name
This entry was named for Georg Simon Ohm.
Linguistic Note
The word abohm is a shortened form of absolute ohm, as evolved from its original full name absolute electromagnetic cgs unit of resistance.
