Abohm Today

) is a unit of electrical resistance used in the system of units, specifically the electromagnetic version. In terms of scale, an abohm is incredibly small: 1 abohm = 10-910 to the negative 9 power ohms (or one billionth of an ohm).

The term "abohm" was introduced around by Arthur Edwin Kennelly. The "ab-" prefix stands for absolute , a nod to the "absolute electromagnetic system" used at the time. ) is a unit of electrical resistance used

This is exactly equivalent to in the modern SI system. The "ab-" prefix stands for absolute , a

The Ghost in the Circuit: A Look at the Abohm If you’ve spent any time looking at electrical units, you’re probably familiar with the , the standard unit of electrical resistance.
