Abohm File
Technically, a conductor has a resistance of one abohm if a current of one flowing through it produces a potential difference of one abvolt across its ends. A Quick History Lesson
While it might sound like a specialized term from a sci-fi novel, the abohm is a very real—though now dated—unit that once played a key role in how we measured the world. What Exactly is an Abohm? The abohm (
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. Technically, a conductor has a resistance of one
With the rise of the , specialized units like the abohm became obsolete. Modern standards, such as those from the IEEE and Merriam-Webster , typically label it as "dated" or recommend using the standard ohm instead. How to Convert It
This is exactly equivalent to in the modern SI system. The abohm ( The term "abohm" was introduced
) 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).
If you ever find yourself looking at old lab notes or vintage scientific papers, you might need to convert these units. You can use tools like the Inch Calculator for quick math, but the basic formula is simple: ABOHM Definition & Meaning - Merriam-Webster Modern standards, such as those from the IEEE
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. But hidden in the attic of scientific history is its tiny, nearly forgotten ancestor: the abohm .
